 * I am receiving this message and wondering how to fix:
 *     ```
       <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
       <html><head>
       <title>404 Not Found</title>
       </head><body>
       <h1>Not Found</h1>
       <p>The requested URL was not found on this server.</p>
       <p>Additionally, a 404 Not Found
       error was encountered while trying to use an ErrorDocument to handle the request.</p>
       </body></html>
       ```
   
 * I am trying optimise my data in Yoast. I have tried debugging in wp-config.php
 *     ```
       // Enable WP_DEBUG mode
       define( 'WP_DEBUG', true );
   
       // Enable Debug logging to the /wp-content/debug.log file
       define( 'WP_DEBUG_LOG', true );
   
       // Disable display of errors and warnings
       define( 'WP_DEBUG_DISPLAY', false );
       @ini_set( 'display_errors', 0 );
   
       // Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
       define( 'SCRIPT_DEBUG', true );
       ```
   
 * and this didn’t help.
 * Thanks Tony

 * Moved to Fixing WordPress, this is not an Everything else WordPress topic.
 * Please ask plugin specific questions in that plugin’s dedicated sub-forum instead.

 * If anyone ever experiences this problem, just head to WP Permalinks and ‘save
   changes” fixes straight away!
