 * Hi, see in mij WP admin an error message/warning: “Er is een firewallregel ingeschakeld,
   maar de firewall lijkt niet goed te worden geladen. Controleer of het bestand
   advanced-headers.php is opgenomen in wp-config.php en bestaat in de map wp-content.”
   
   I checked the folder wp-content and the file advanced-headers.php exists, but
   is not mentioned in wp-config.php.What is the exact php code to use in wp-config.
   php to refer properly to advanced-headers.php?Thanks!

 * Hi [@wordpressthijs](https://wordpress.org/support/users/wordpressthijs/),
 * Please try adding the following lines, under the opening **<?php** tag in the
   wp-config.php file:
 *     ```
       if ( file_exists(ABSPATH . "wp-content/advanced-headers.php") ) { 
       	require_once ABSPATH . "wp-content/advanced-headers.php";
       }
       ```
   
 * Kind regards, Jarno
