 * You can enable debugging in WordPress:
    1. Edit your wp-config.php 2. Search 
   for: `define('WP_DEBUG', false);` 3. Replace with: `define('WP_DEBUG', true);`
   4. Add this line below: `define( 'WP_DEBUG_LOG', true );`
 * Try to run the “Full WAF” installer again and, after you see the 503 error, check
   the debug log which will be located in “/wp-content/debug.log”.`
