How to Fix HTTP Error 405 Method Not Allowed Error?

To fix the HTTP 405 Method Not Allowed Error, here are some methods you can use to resolve this HTTP error:

Solution 1: Check the URL

You have to ensure the URL is correct because the most frequent reason for a 405 Method Not Allowed error is inputting an incorrect URL.

Solution 2: Revert Recent Updates

If the 405 Method Not Allowed error message began showing up right after you updated WordPress, try reverting the update.

Pewrhaps the newly implemented code might be causing the issue.

Solution 3: Check for Database Changes

Pinpointing this specific issue can be challenging, but if you believe that a plugin or theme might be triggering the 405 Method Not Allowed error, your best bet is to inspect your database directly.

Look for any recent changes in the database that might be causing the error.

To do this, you’ll have to access your site’s database and manually examine the tables and records altered by the extension.

If you’re uncertain about what to search for, it would be wise to consult your developer at this stage (and for the subsequent steps on this list).

Solution 4: Uninstall New Plugins, Themes, and Extensions

If the error started after installing a new plugin, theme, or extension, try uninstalling it.

Plugins and themes are vital to any WordPress website, enhancing its functionality and aesthetics.

However, these new plugins, themes, and extensions can sometimes cause issues, like the 405 Method Not Allowed error, due to their impact on site operations or potential conflicts with other site elements or your WordPress version.

Uninstalling certain plugins or themes could potentially resolve this error.

You can start this process by going to the Plugins section of your WordPress dashboard, where you’ll find a list of all installed plugins.

Solution 5: Check Your Server-Side Logs

Server logs can provide clues about what’s causing the error.

A web application maintains logs on the server side to monitor various activities and events on your site.

Alterations in these server logs can trigger the 405 Method Not Allowed error on your website.

It’s important to review your server logs to verify the accuracy of all information.

To view your site’s server logs, navigate to your root directory and search for the files named access.log and error.log.

Examine the information in these files for any discrepancies.

Solution 6: Check Your Web Server Configuration

If the 405 Method Not Allowed error continues, inspect your server configuration files.

This error suggests that the server setup restricts access to a specific URI.

Examine your server software for any unintended redirects or instructions for handling requests.

To do this, identify the server software your site uses, typically Apache or NGINX.

For Apache servers, search for a .htaccess file in your website’s root directory.

For NGINX servers, look for an nginx.conf file. In these files, look for directives using a 405 flag.

Revert any changes to these files, restart your server, and see if the error is resolved.

Solution 7: Check Your Code and Scripts

If all the previous measures haven’t resolved the issue, it could indicate a problem with custom code in your WordPress setup.

Debugging is the only method to confirm if this is the source of the 405 Method Not Allowed error.

Fixing this error involves examining the website’s code and scripts, ensuring they’re in the appropriate programming language.

You can do this by duplicating the website onto a local development machine and running a debugging process that replicates the exact situation where the 405 Method Not Allowed error happens.

This method simplifies pinpointing the exact moment of error occurrence.

Solution 8: Fully Restore Your Website From a Backup

The HTTP 405 error often emerges from compatibility problems.

If other solutions haven’t rectified this issue, consider restoring your website from the latest backup.

If you have a backup of your website, consider restoring it.

Solution 9: Check the .htaccess File

Examine your .htaccess file for any lines that contain 405.

If the .htaccess file is rewritten improperly, it can lead to the appearance of the 405 Method Not Allowed error message on your site.

Incorrect rules in this file can cause the error.

Solution 10: Fix File Ownership

Another factor that could lead to this HTTP method error on your site is improperly configured permissions.

Each file and directory on your website comes with a specific set of permissions.

Rectifying your file ownership can help correct these permission misconfigurations.

Solution 11: Check A Records and DNS

Incorrect DNS records can cause this error.

So to address this HTTP method issue, verify your Domain Name System (DNS) records. Ensure the details in the A records are accurate.

The A record, being the most fundamental type of DNS record, directs a domain or subdomain to an IP address.
