ERROR - Unable to connect to the database

[jorizzzz]

Hi guys,

I've managed to break my ispconfig install again... When I want to add a MySQL database to ispconfig for one of my clients, i get the following error message in /var/log/ispconfig/ispconfig.log:

ERROR - Unable to connect to the database

Adding a FTP user works as well..

I've tested the MySQL user and password from /usr/local/ispconfig/server/lib/config.inc.php and they can login to the ispconfig database. What does this error mean? And more important, how can i fix it?
