I have a unix box, not sure if it is different than windows ~

When you create a database, you have to create a database permission for the database user. Maybe you have forgot to create that?

Also it is better to use a non-root user. If you are running in a shared environment and somebody have access to your config.php file, by using the password, he can wipe out all the databases on your server.

I trashed that old verson of vbulletin. I got sold a bogus copy, i now have a good one that has no problems. People who don't have good computer knowlege should be warned
