vBulletin database error

[dndog]

I keep getting this vBulletin database error email.

Database error in vBulletin :

Link-ID == false, connect failed
mysql error:

mysql error number: 0 

What does it mean, and what can I do to fix it?

This means that either the info in your config.php file is wrong (in which case your forums wouldn't work at all) or there is a problem with the server.

Nothing is wrong with my config.php file (as my forums have been running smoothly for 2 months now).

What would be wrong with my server?

[Steve Machol]

A lot of things could be wrong with it. Is this a dedicated server? If so, for help with optimizing your server, please see this thread:

http://www.vbulletin.com/forum/showthread.php?threadid=70117

Then post the requested info in a new thread in that forum.

If this is not a dedicated server, then you will need to contact your host about this problem.
