I've just activated the Forum module and installed Advanced Forum. My 3 forums and 2 containers work when I browse straight to the forums and containers. The main list doesn't work though. When I go to /forum I get a SQL Error
SQL ERROR [ mysqli ]
Access denied for user 'username'@'hostname.com' (using password: YES) 
An sql error occurred while fetching this page. Please contact an administrator if this problem persists.
Isn't the main forum page supposed to list all the containers and forums like this http://drupal.org/forum? Do I have to enable anything or make a main container to make it do that?
