HI @Hamziatcha This is odd, as the Server Info page is just a fancy wrapper around the php_info() function, which is built-in to PHP. This error message is a generic front-end message, after you see it, be sure to go check your PHP errror logs on your server (often in /var/logs/apache2 on an Apache server), and look for a specific error message. Let us know what you find so we can help fix it. Thanks!
