Fixing the HTTP 405 Method Not Allowed Error on WordPress Sites

Few things are more frustrating than updating a page, submitting a contact form, or logging into your website only to be greeted by an error message. The WordPress 405 method not allowed error can appear without warning, even when your site seemed to be working perfectly moments earlier.

The good news is that this issue is usually fixable. In many cases, the server is rejecting a specific request because of a plugin conflict, a misconfigured file, or a security rule. Understanding why the error occurs is the first step toward resolving it.

What Does the WordPress 405 Method Not Allowed Error Mean?

When you browse the internet, your browser constantly sends requests to a web server. These requests use different HTTP methods, which tell the server what action should be performed.

Some common methods include:

• GET: Retrieves information from a webpage.
• POST: Sends information, such as form data.
• PUT: Updates existing content.
• DELETE: Removes data.

A 405 error means that the server understands the request but refuses to allow that specific method for the selected resource.

Think of it like visiting the correct office building but asking the receptionist for a service handled by another department. You are in the right place, but the requested action is not allowed there.

Why Does WordPress Reject Certain Requests?

A WordPress website relies on several layers working together:

1. Your browser sends a request.
2. The web server receives it.
3. WordPress processes the request.
4. Plugins and themes handle the action.
5. The server sends back a response.

If something interrupts this process, the server may return a 405 response instead of loading the page.

Common causes include:

• Plugin conflicts
• Incorrect theme code
• Corrupted .htaccess rules
• Web application firewalls
• Improper server settings
• Caching problems
• Broken redirects
• REST API restrictions
• File permission issues

The error message itself rarely explains which component is responsible, so troubleshooting requires a step-by-step approach.

WordPress 405 Method Not Allowed vs Other HTTP Errors

Error Code	Meaning	Where to Check
403 Forbidden	Access is denied	Permissions and security rules
404 Not Found	Resource cannot be found	URLs and deleted pages
405 Method Not Allowed	Server rejects the request method	Plugins, forms, server rules
500 Internal Server Error	Server failed to complete the request	PHP errors and configuration

Understanding the difference matters because a solution that fixes a 404 error may not help with a 405 response
.

Before You Start Troubleshooting

Before changing settings, create a complete backup of your website.

If possible, test fixes on a staging site rather than directly on your live website. It is also helpful to note:

1. Which page triggers the error

2. Whether the problem occurs after a plugin update

3. Whether logged-in users are affected

4. Whether the issue appears in different browsers

5. The exact action that triggers the error

These details can save hours of troubleshooting.

How to Fix the WordPress 405 Method Not Allowed Error

1. Refresh the Page and Clear Caches

Start with the simplest fix.

Clear the following caches:

1. Browser cache
2. WordPress caching plugins
3. CDN cache
4. Server cache
5. Object cache

After clearing the cache, open the affected page in a private browsing window and test it again.

Sometimes cached files contain outdated instructions that conflict with newer requests.

2. Check for Plugin Conflicts

Plugins can change how WordPress handles forms, redirects, AJAX requests, and API calls. A single plugin conflict may cause the server to reject a valid request.

To test plugins:

1. Open your WordPress dashboard.

2. Deactivate all plugins.

3. Test the affected page.

4. Reactivate plugins one by one.

Pay special attention to:

• Security plugins

• Contact form plugins

• Redirect managers

• Membership tools

• Caching plugins

• REST API restriction plugins

Real-World Example

Imagine that a customer submits a contact form on your business website and receives a 405 error. After disabling a recently installed security plugin, the form starts working again. The plugin was blocking the POST request rather than the form itself.

For a more detailed walkthrough of plugin and server troubleshooting, this guide on 405 method not allowed WordPress error explains additional debugging steps.

3. Test Your Theme

Themes do much more than control your website's appearance. Many include:

1. Custom forms
2. AJAX features
3. Page builders
4. Login templates
5. Registration pages
   

Switch temporarily to a default WordPress theme and test the page again.

If the error disappears, inspect:

1. Custom code in functions.php
2. Form templates
3. AJAX handlers
4. Theme integrations

Check the .htaccess File

On Apache servers, WordPress uses the .htaccess file to manage URLs and redirects. Incorrect rules can block legitimate requests.

Start by refreshing permalinks:

1. Go to Settings → Permalinks.
2. Keep the existing structure.
3. Click Save Changes.
4. Test the page again.

If the issue persists:

• Download a backup of .htaccess.
• Rename the existing file.
• Save permalinks again.
• Let WordPress generate a fresh file.

Even a small mistake inside .htaccess can cause unexpected errors.

Verify Which Server You Are Using

Not all hosting environments work the same way.

Your website may run on:

1. Apache
2. Nginx
3. LiteSpeed
4. A mixed Apache–Nginx setup

For example, .htaccess only affects Apache-based servers. Nginx stores rewrite rules in server configuration files instead.

Understanding your hosting environment can make troubleshooting much easier. Many website owners review the features available in different WordPress hosting plans to better understand how backups, logs, caching, and server settings are managed.

Review Error Logs

Error logs act like a security camera for your website. Instead of guessing, you can examine what happened when the request failed.

Check:

1. WordPress debug logs
2. PHP logs
3. Apache logs
4. Nginx logslllllllllllllllllll
5. Firewall logs
6. Security plugin activity logs
7. CDN logs

To enable WordPress debugging, add the appropriate configuration settings to wp-config.php.

Remember to disable debugging after you finish troubleshooting.

Check Firewall and Security Rules

Many websites use security layers that filter suspicious traffic. Sometimes, these protections block legitimate requests.

Ask your hosting provider to inspect:

• ModSecurity rules
• Web application firewalls
• Reverse proxy settings
• REST API restrictions
• Request filtering rules
• File permissions

Real-World Example

An online store loads product pages normally, but checkout fails with a 405 response. Plugins and themes appear fine. Later, the hosting company discovers that a firewall rule is blocking checkout requests. Updating that rule resolves the issue without affecting site security.

Inspect Custom Forms and API Requests

Developers sometimes create custom forms or integrations that send data to the wrong destination.

Check the following:

• Form action URL

• Request method

• Security tokens

• AJAX endpoints

• REST API routes

• Redirect settings

You can also use Chrome Developer Tools:

1. Press F12.

2. Open the Network tab.

3. Reproduce the error.

4. Inspect the failed request.

Look for:

• The request type

• The destination URL

• Response headersc

• Error codes

Avoid changing POST requests into GET requests simply to bypass the error. Some actions require POST requests for security reasons.

Common Mistakes to Avoid

Editing Live Files Without a Backup

A small configuration mistake can turn a simple error into a completely inaccessible website. Always create backups first.

Disabling Everything at Once

Turning off multiple plugins and settings simultaneously may hide the problem without revealing its cause. Test one change at a time.

Repeatedly Submitting Forms

Submitting forms repeatedly can create duplicate orders, messages, or payment attempts.

Copying Random .htaccess Rules

Code snippets found online may not match your server environment.

Disabling Security Permanently

Security plugins and firewalls exist for a reason. Identify the exact rule causing the problem instead of removing protection entirely.

Ignoring Server Logs

Logs often reveal the plugin, file, or configuration responsible for the error.

FAQs

1. Is the WordPress 405 method not allowed error caused by my browser?

Usually, no. The problem often originates from the website, plugins, or server configuration. However, testing another browser can help rule out local issues.

2. Can a plugin trigger a 405 error?

Yes. Security, caching, redirect, and form plugins can interfere with HTTP requests and block them unexpectedly.

3. Will resetting permalinks solve the problem?

It can help if corrupted rewrite rules are responsible. However, permalink changes will not fix firewall or plugin conflicts.

4. Should I delete the .htaccess file?

No. Always create a backup before making changes. Renaming the file temporarily is safer than deleting it.

5. Why does the error only appear after submitting a form?

Most forms use POST requests when submitting data. A plugin, firewall, or server rule may block that method while still allowing normal page views.

6. How can hosting support help?

Hosting providers can review logs, firewall settings, and server configurations that are not accessible from the WordPress dashboard.

Conclusion

The WordPress 405 method not allowed error means that the server understands a request but refuses to allow that action. Although the message may seem technical, the solution is often straightforward once you identify whether the problem comes from plugins, themes, rewrite rules, or server settings.

Start with simple checks, work methodically, and avoid making major changes without backups. If you want to learn more about the hosting tools and features that can simplify WordPress troubleshooting, explore the WordPress hosting resources linked above.

How to Fix the ERR_CACHE_MISS Error in Google Chrome

Seeing the Fix ERR_CACHE_MISS Chrome message on your screen can be frustrating, especially when you are trying to submit a form, open a website, or continue browsing. The error often appears suddenly and may leave users wondering whether their browser or internet connection is broken.

Fortunately, the issue is usually related to stored browser data, network settings, or extensions. In most cases, you can solve it in a few minutes without advanced technical knowledge. This guide explains the common causes and practical solutions in simple terms.

What Does ERR_CACHE_MISS Mean in Chrome?

Google Chrome stores temporary files, images, and website data in a cache. Think of the cache as a small storage room that helps websites load faster by remembering information from previous visits.

The ERR_CACHE_MISS error appears when Chrome cannot retrieve or verify cached data properly. It often happens when:

• A website requests information that is no longer available in the cache.

• Browser data becomes corrupted.

• Network settings interfere with page loading.

• Extensions block or modify web requests.

• A form submission fails or times out.

Although the message sounds serious, it usually indicates a communication problem between Chrome and the website rather than damage to your computer.

Common Situations Where the Error Appears

You may encounter this error in different scenarios:

• Refreshing an online form after clicking "Submit."

• Returning to a previous page with the browser's Back button.

• Accessing websites after a Chrome update.

• Using shopping carts or payment pages.

• Opening websites while certain extensions are active.

Real-World Example 1

Imagine filling out a job application form. After entering all your details, you press the Back button to review something and suddenly see the ERR_CACHE_MISS message. Chrome may be trying to reload information that is no longer stored correctly.

Real-World Example 2

Suppose you frequently use ad blockers and privacy extensions. One extension blocks a website script that Chrome expects to load from its cache, resulting in the error.

Quick Comparison of Troubleshooting Methods

Solution	Difficulty Level	Time Required	Best For
Reload the page	Easy	1 minute	Temporary glitches
Clear browser cache	Easy	5 minutes	Corrupted browser data
Disable extensions	Easy	5–10 minutes	Extension conflicts
Reset network settings	Medium	10 minutes	Internet-related issues
Reset Chrome settings	Medium	10–15 minutes	Persistent problems

Method 1: Reload the Page

Before trying advanced fixes, refresh the webpage.

You can:

• Press F5.

• Click the refresh icon.

• Press Ctrl + Shift + R for a hard refresh.

A hard refresh forces Chrome to load the latest version of the page instead of relying on stored files.

If the problem disappears, the error was likely caused by outdated cache data.

Method 2: Clear Chrome Cache and Browsing Data

Old or corrupted browser files are among the most common reasons for this issue.

Follow these steps:

1. Open Chrome.

2. Click the three-dot menu in the top-right corner.

3. Select Delete browsing data.

4. Choose Cached images and files.

5. Optionally select cookies and browsing history.

6. Click Delete data.

Restart Chrome and revisit the website.

Users looking for a more detailed walkthrough can refer to this guide on ERR_CACHE_MISS chrome fix , which explains additional troubleshooting steps.

Method 3: Disable Browser Extensions

Extensions improve Chrome's functionality, but some can interfere with website caching and network requests.

Common examples include:

• Ad blockers

• VPN extensions

• Privacy tools

• Download managers

• Security add-ons

To disable extensions:

1. Type chrome://extensions/ in the address bar.

2. Press Enter.

3. Turn off all extensions.

4. Restart Chrome.

5. Test the website again.

If the website works normally, re-enable extensions one by one until you find the problematic one.

Method 4: Reset Chrome Network Settings

Sometimes the issue has nothing to do with the browser cache. Incorrect network settings may interrupt communication between Chrome and websites.

Flush DNS Cache on Windows

1. Open Command Prompt as administrator.

2. Type:

ipconfig /flushdns

3. Press Enter.

You should see a message confirming that the DNS cache has been cleared.

Reset the Network Stack

Run these commands one by one:

netsh winsock reset

netsh int ip reset

Restart your computer after executing the commands.

If you manage websites or frequently troubleshoot browser issues, resources provided by Onlive Server hosting can help you better understand how browsers, servers, and network configurations interact.

Method 5: Disable Cache Temporarily in Chrome Developer Tools

This solution can help determine whether the cache is responsible for the problem.

Follow these steps:

1. Open the affected webpage.

2. Press F12.

3. Open the Network tab.

4. Check Disable cache.

5. Refresh the page.

Keep in mind that this setting only works while Developer Tools remains open.

Method 6: Reset Chrome Settings

If multiple websites display the error, resetting Chrome may help.

To reset Chrome:

1. Open Chrome Settings.

2. Click Reset settings.

3. Select Restore settings to their original defaults.

4. Confirm the reset.

This action removes temporary configurations but keeps bookmarks and saved passwords.

Method 7: Update Google Chrome

Using an outdated browser version can sometimes trigger compatibility problems.

To update Chrome:

1. Open the Chrome menu.

2. Select Help.

3. Click About Google Chrome.

4. Allow Chrome to search for updates.

5. Restart the browser if an update is available.

Regular updates improve security and fix known bugs.

Method 8: Check for Form Submission Issues

The ERR_CACHE_MISS message often appears after submitting forms.

This happens because some websites prevent users from resubmitting the same information accidentally. Chrome then asks for confirmation or fails to retrieve the original data.

To avoid this issue:

• Avoid repeatedly pressing the Back button after submitting forms.

• Save important information before submission.

• Refresh the page before entering data again.

• Open important forms in a new tab.

Why Browser Cache Exists in the First Place

Many users assume cache files are harmful because they occasionally cause errors. In reality, caching improves performance.

Without caching:

• Websites would load more slowly.

• Images would download every time.

• Browsers would use more bandwidth.

• Pages would feel less responsive.

The cache acts like a notebook that helps Chrome remember previously visited content. Problems arise only when stored information becomes outdated or inconsistent.

Common Mistakes to Avoid

While trying to solve the issue, users often make things worse. Avoid these mistakes:

• Clearing passwords without backing them up.

• Installing random "PC repair" software.

• Disabling antivirus programs unnecessarily.

• Resetting the entire operating system before testing simple fixes.

• Ignoring browser updates.

• Using too many extensions at the same time.

Start with basic troubleshooting before moving to advanced solutions.

How to Prevent ERR_CACHE_MISS in the Future

You cannot completely eliminate browser errors, but you can reduce the chances of seeing them again.

Helpful habits include:

• Keep Chrome updated.

• Remove unused extensions.

• Clear cache periodically.

• Avoid force-refreshing forms repeatedly.

• Restart the browser occasionally.

• Use trusted websites and extensions.

Small maintenance steps can prevent many browser-related issues.

FAQs

1. Is ERR_CACHE_MISS caused by a virus?

Usually, no. The error is generally related to browser cache problems, extensions, or network settings rather than malware.

2. Does clearing cache delete passwords?

Not necessarily. Chrome allows you to choose which data to remove. If you select only cached files, your saved passwords remain intact.

3. Why does ERR_CACHE_MISS appear during form submissions?

Many websites block duplicate submissions. When Chrome cannot retrieve the original form data, the error may appear.

4. Can extensions cause the problem?

Yes. Ad blockers, VPNs, privacy tools, and other extensions sometimes interfere with Chrome's caching process.

5. Will resetting Chrome delete bookmarks?

No. Resetting Chrome settings restores defaults but generally keeps bookmarks and saved passwords.

6. Does the error mean the website is down?

Not always. The problem often originates from your browser, cache, or network configuration rather than the website itself.

7. Should I reinstall Chrome?

Reinstalling Chrome should be your last option. Most users can solve the problem by clearing cache, disabling extensions, or resetting settings.

Conclusion

Learning how to Fix ERR_CACHE_MISS Chrome problems does not require advanced technical skills. In most cases, clearing browser data, checking extensions, resetting network settings, or updating Chrome resolves the issue quickly.

Because the error can appear for several different reasons, it is best to try the simplest solutions first and move step by step toward more advanced troubleshooting. For additional resources and browser-related information, you can explore the guides available on Onlive Server's website.
