I've been having a few problems with the database and I'm not sure how to restart and fix it. It's weird.

Anyway, I have a few sites running on Wordpress and they can connect to the database fine. But when I went into Fantastico to install Wordpress, the new ones can't connect to the database. A site that had vBulletin running on it can't connect but a site running on phpBB can.

Does anyone know how I can take care of the MySQL and stuff? Any help will be greatly appreciated!
