Step 5: Edit your browser in Incognito mode. Thanks to this, you can solve the problem with the browser cache or an add-on.

In case it is missing, let go to “Settings Permalinks Screen” on the official WordPress page to recreate. You need also check whether your server deletes the PHP $_GET variable or not.

 Step 11. HTTP Errors.

In case you get 403 errors, let’s follow this instruction:

It will build automatically a new default .htaccess file for your site. In case your problem is solved, you should check the .htaccess file that you downloaded to find out whether it has any code needing to correct.

The problem may deter form incorrect permission. So let contact your hosting company to check whether the listing and file on your WordPress site have the correct permissions.

A security plugin may be the reason for this problem. In order to tackle this, try to contact the support team or turn on the learning mode of the plugin.

Another plugin may be the reason. In this situation, you need to turn off all plugins except Elementor Page Builder.
