Once you’ve made the backup, it’s time to troubleshoot the error. Let’s begin.

1. Enter The Correct URL

Entering the wrong URL is one of the most common reasons behind the 405 methods not allowed error in WordPress.This happens because web servers keep users from accessing the wrong pages by disallowing access to invalid URLs.

Updates generally bring in a pack of new exciting features and bug fixes but there are times when they become a root cause of frustrating errors on your WordPress site. It’s the same in the 405 methods not allowed error.

If you’ve recently updated your WordPress version before the 405 error occurred, there’s a high chance that it might be causing the problem.

3. Uninstall Recently Added Plugins Or Themes

Plugins are the main reason why WordPress is so insanely popular. In simpler words, they’re the backbone of your website. However, here’s the catch. Plugins and extensions are also the reason why many WordPress sites crash every day. This is because there are plugins that might conflict with the theme of your website or any other element.

If you’ve recently installed a plugin before facing the 405 error, it may be the root cause. To solve the error here, you need to uninstall any recently installed theme or plugin from your WordPress site. Since WordPress boasts over its plugin directory of more than 45,000 plugins, you’d definitely find an alternative to the culprit.

It is always a great practice to choose themes are plugin that is premium. This is because these extensions are aligned with the latest protocols. If you’re looking for free alternatives, then it is essential to check out ratings and reviews of the plugins.

4. See If There Are Any Database Changes

Even though switching the plugins and extensions may resolve your 405 error, but there are times when the changes made by these extensions aren’t reverted from your database. This is because as soon as install a plugin to your WordPress site, they dig deep into your site’s database and make changes.

Now diagnosing and resolving this problem is quite tricky. To check your database, you need to manually check out all the records and tables modified by the plugin. We’d suggest you hire a WordPress maintenance company to do the job for you.

5. Check Your Server’s Configuration

Checking your web server software’s configuration files for any unintentional handling instructions may help to determine the root cause of the 405 Method Not Allowed error.

First, you need to determine which application is used by your web server. If it’s running Apache, you should be able to find a .htaccess file within the root directory of your website’s file system.

When your application is on a shared host, you’ll likely have a username associated with your particular account. If that’s the case, the application root directory can typically be found by following this path.


Therefore, you’ll find the .htaccessat


Once you’ve found the .htaccess file, open it up in the text editor and navigate to the lines using Rewrite detectives. These are part of the mod_rewrite module in Apache and define a text-based pattern that will be matched against all entered URLs. If a matching URL is requested by a visitor to your site, the RewriteRule will redirect the visitor appropriately.

Here’s an example of the RewriteRule

RewriteCond %{HTTP_HOST} !^(www.)?example\.com$

RewriteCond %{REQUEST_URI} ^/bar/ [OR]

RewriteCond %{REQUEST_URI} ^/test/

RewriteCond %{REQUEST_URI} !=/favicon.ico

RewriteRule(.*) /index.php [L]

Again, this is a tricky process, therefore letting a WordPress maintenance service provider handle it would be a better option.
