You can freely choose any way to back up files, either with the help of plugins, using Dropbox, or manually through cPanel. If so, let’s get to the point of the discussion below:  

1. Downgrade WordPress to the Previous Version

Having the latest version of WordPress is important. The benefits can affect many things. Starting from the use of smoother, overcome bugs or annoyances, and support a variety of new features that are qualified.

However, despite its many benefits, updating can sometimes cause problems.

If you have just updated WordPress and the error 405 Method Not Allowed error issue appears, the root might be in your latest version of WordPress. So the steps you can take are to downgrade WordPress to the previous version. 

Although you can do this manually, it will be more effective if you use a plugin.

Of all the plugins available, the WP Downgrade plugin is still an effective choice. This plugin automates each process, so it is less likely for you to make a mistake. But, don’t forget to keep backing up all your files first, yes!

If after WordPress downgrade and the error is lost, it means that the root is indeed in the new version of WordPress. However, if you already downgrade and the error still appears, it means the cause of the error is not the WordPress version. You can follow the next solution.

2. Disable Some Plugins 

Plugins can also be the cause of this error. Just like updating the latest version, plugins that have been installed are sometimes vulnerable to cause problems. This is because every time a new function is added to the site, the way the system operates will also change. 

Or it could also be a result of the default plugin, which does not match your current WordPress version. So, as a solution, try to deactivate some of your plugins in the way below:

  • Open your WordPress admin dashboard.
  • Select Plugins from the menu in the left sidebar, and check each plugin to be deactivated.

If all plugins have been deactivated and an error still appears, it means that the cause of the error did not come from the plugin. It could be the cause is the theme you are using. For that, you can follow the next solution to deactivate the theme. 

3. Disable Themes

Similar to what happens in plugins, these changes can sometimes trigger errors on your website. Therefore, try to change your theme in the following ways:

  • Open your WordPress admin dashboard.

If the plugin or theme is the trigger for the error 405 Method Not Allow error, you can delete it or replace it with another option. We also recommend that you report this issue to their developers so that it can be resolved immediately.

4. Check if there are any accidental changes to the database. 

Although the steps above should have been quite effective, that does not fully guarantee that the error will instantly disappear.

Because installed plugins have access to enter your database, this means that it is possible that the plugin can change database settings without your knowledge. As a result, this database change is the cause of error 405 Method Not Allowed.

Finding out the location of database changes will be very troublesome. This requires considerable time-consuming efforts. You need to access the database in your WordPress, check one by one, and make sure if the plugin has changed anything. 

If you find it difficult to do it yourself, you can ask for help from developers or professionals to overcome them. 

In the future, you can also use security plugins like iThemes Security. This plugin can give you notifications when you find changes in the database. 

Or you can also install other security plugins that have a database logging feature. This feature will usually help you to find obstacles in the database quickly and easily.

5. Check Website Server Configuration Settings

The next way is to check the configuration settings on your web server. Most websites use a web server from two popular softwares, Apache or Nginx. Below, we will guide you to check the webserver configuration settings of both software. 

5.1. Check the Configuration File in Apache

If your website server uses Apache, you will find a file with the format. Htaccess. Next, you can check the configuration settings in the file. Here is how:

  • Open your website’s root directory via cPanel.
  • Open the File Manager folder.
  • Search for the file with the format. Htaccess in the search field. If you use a shared hosting service, you can search for files with the format: /home/public_html/.htaccess.
  • Open the file using a text editor such as Notepad.
  • Look for a line of code that says Rewrite. Rewrite is here that serves to direct visitors to the right website page according to the URL address.
  • Check whether there is a sequence of Rewrite codes ending in code [R = 405]. For example, like this.

  • If you find the code, add the # fence character in the row.
  • Restart your webserver again. Then refresh the web page again whether the error has successfully disappeared or not.

5.2. Check the Configuration File in Nginx

How to check configuration files with the Nginx web server will be the same as Apache. It’s just that you need to look for files in the nginx.conf format

  • To easily find the nginx.conf file format , you can check in several directory folders such as: / usr / local / nginx / conf , / etc / nginx , or  / usr / local / etc / Nginx .
  • If you have found, open the file with a text editor.
  • Find the line of code that includes the 405 number like the following example.
