All my vBulletin/vBadvanced sites Homes Suddenly Down. MySQL Problems

[sublo]

Hi All. I need help desperately. My sites are on one colocated virtual server. They were working yesterday. I made no changes. All the vBulletin/vBadvanced Home pages are suddenly down! the http://blaablaablaa.blaa/forums are still up. What happened????

Here are the sites: http://www.camillegerard.com, http://www.stjosephforums.org

Please, please help. MySQL is indeed up and running. I tried restarting the daemon as well as rebooting the server. No luck.

Help!

Here is the error:
