 * I installed WordPress for the first time yesterday along with Wordfence and Elegant
   Themes’ Divi theme. I had Jetpack running briefly, but disabled it for the time
   being.
 * Today, Wordfence listed two “critical” issues, which are detailed below. As a
   newbie, I’m hoping you can tell me whether these issues should be acted upon 
   or ignored.
 * Issue 1
    WordPress core file modified: wp-includes/version.php
 * The Original Version of the file
 *     ```
       33	* @global string $required_mysql_version
       34	*/
       35	$required_mysql_version = '5.0';
       ```
   
 * The Modified Version on your WordPress system
 *     ```
       34	*/
       35	$required_mysql_version = '5.0';
       36	$wp_local_package = '';
       ```
   
 * Issue 2
    WordPress core file modified: wp-admin/includes/upgrade.php
 * The Original Version of the file
 *     ```
       285	https://wordpress.org/
       286	"), $blog_url, $name, $password);
       287
       288	   @wp_mail($email, __('New WordPress Site'), $message);
       ```
   
 * The Modified Version on your WordPress system
 *     ```
       285	https://wordpress.org/
       286	"), $blog_url, $name, $password);
       287
       288	   //@wp_mail($email, __('New WordPress Site'), $message);
       ```
   
 * Thanks in advance for any advice you can provide.

 * I have the same issue as issue 1.
 * It looks like Wordfence is not correctly checking [http://nl.wordpress.org/](http://nl.wordpress.org/)
   in the repository.
 * Maybe you have updated to WordPress to v3.9.1, but not updated the Dutch files
   from [http://nl.wordpress.org/](http://nl.wordpress.org/).

 * Download de Nederlandse versie en overschrijf deze op je server via FTP.
 * Nadat dit compleet is moet je in het wp-config.php bestand, welke zich in de 
   root van je WordPress installatie bevindt, een kleine aanpassing doen. Zoek de
   volgende code op:
    define (‘WPLANG’, ”); en verander dit naar define (‘WPLANG’,‘
   nl_NL’);
 * Sla het bestand op en upload het weer terug naar de plek waar je het gevonden
   hebt.
