the source of the error I think is

Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) in /var/www/html/forums/admin/db_mysql.php on line 34

all vBulletin errors should be addressed on the vb.com support forums, not the hacking forums.

please go to the Troubleshooting and Problems forum
http://www.vbulletin.com/forum/forumdisplay.php?s=&forumid=38

Though it looks like mysql needs restarted.
