fixed
Hi,
i face the same problem, when using wamp, the password for root is empty (no password). what you have to do is, put password for the root account using phpmyadmin and change the config in the ost-config.php.
//empty password
define('DBPASS','');
//with password.
define('DBPASS','YOURPASSWORD');
then the problem is solved.
------------------------------------
actually, osticket does not allow empty password. i found this in line 23, mysql.php
if(!strlen($dbuser) || !strlen($dbpass) || !strlen($dbhost))
return NULL;
this is the main reason.
