What Are the Best Methods to Solve the Request Method' Post' Not Supported Error?

Try the following methods to solve this error.

Confirm That Your Input URL Is Correct

The wrong URL is the primary cause of this error, as web servers prevent visitors from accessing the wrong pages. Therefore, you should check it to confirm that all is good. Be sure to confirm that your spelling is correct and that you've included all letters.

Confirm if You Have Database Changes

Plugins can modify database records under WordPress without notice. When you uninstall such plugins, they can't revert the earlier changes; instead, they ignore them. This condition may result in Request Method' POST' Not Supported error when left unaddressed.

Therefore, you need to check your database to see the changes. You can do this by opening the database and going through the table to identify the plugins' changes. If you find this process challenging, seek help from your web developer.

Check the Server's Configuration

You should check your website server's configuration for usage instructions that may help identify the cause of the error.

To do so, follow the steps listed below.

  • The first step is to establish the application your web server is using.
  • To do so, look for a key file like the .htaccess file (Apache). However, if you are running on a shared host, you can locate the application root directory by inputting _ /home/public_html/. _ This will direct you to _ /home/public_html/.htaccess, _ where your .htaccess file is.
  • Proceed to open the .htaccess file in a text editor.
  • Find lines with Rewrite directives. This RewriteRule directs a browser URL request to the appropriate page when the URL matches your web server protocol.
  • However, if you notice any strange Rewrite directives, comment with the _ # _ prefix.
  • Restart your web server. This should solve the problem.

Undo Your Recent WordPress Updates

WordPress update can result in the Request Method' POST' Not Supported error, especially if the error shows up after your recent update. If this is the case, you may need to restore the previous WordPress version. However, before you restore the previous version, ensure you backup your website.

You can do so manually or use a plugin like WP Downgrade. However, the effective way to update is by using the plugin, which automates the process.

If this process doesn't solve the error, you can restore your backup, re-update the website, and probably try a different method.

Debug Your Application Code

This method should be the last option when all the other methods have proven ineffective. Debugging your code or scripts will address the Request Method' POST' Not Supported error if the error generates from the WordPress installation custom code.

But before you do anything, back up your installation in a development area.

After backing up, proceed to debug the code. Note that this process will vary depending on the software and website. You need to follow the procedure step-by-step as it does not have a shortcut.

Proactively Monitor for Errors
