Here at Bobcares, we have seen several such WordPress errors as part of our Server Management Services for web hosts, WordPress users, and online service providers.

Today we’ll take a look at the cause of this error. Also, let’s see how our Support Engineers resolve it.

What Causes 405 Method Not Allowed Error to occur

There can be different reasons for this error to occur. A few such causes are:

• Entering the wrong URL
• Faulty plugins and themes
• Recent WordPress updates
• Certain database changes

How to troubleshoot 405 Method Not Allowed Error in WordPress

Here are some of the steps our Support Engineers follow to tackle this error message.

1. Check if you are accessing the Correct URL

Entering an incorrect URL is one of the common causes for 405 errors to occur. So we need to check if we are accessing the right website URL.

We make sure to check misspelling a word or letter.

2. Roll Back Any Recent WordPress Updates

Sometimes, a few updates may crash the website due to certain incompatibility issues. So it would be a great idea to revert back the changes. For that, we can make use of any recent backups available on the server.

3. Uninstall New Plugins and Themes

Plugins and themes provide great features to the website. However, they can also cause some issues to the website as well.

So we can try disabling them temporarily and check if the website starts working back normally.

4. Check for Any Unexpected Database Changes

This step might seem to be a little difficult. You can check the database directly by opening the site’s database, and manually look through the tables and records modified by the extension. If you’re not sure what to look for, you can get in touch with our Support Engineers anytime.
