vBulletin Database Error

[Shadow]

Alright, for the past hour or so, my site has been spitting out Database Errors. Now, the problem is, i don't know how to fix this because the email that is used for sending the DB Error logs isn't receiving the emails.

So now, i'm stuck with a non working website and confused members. Any suggestions guys?

Thanks in advance.

EDIT: Just to let you know, the most recent site/server change was to the "php.ini" file to increase the Maximum Memory Limit. No other changes have been made recently.
