Hi Guys

Need a little help please, I did post this a few months ago and I thought my server people had fixed it but I am getting around 20 or more of these emails a day and till now I have put up with it but I can't anymore!

This is a copy of the error I am getting:

Database error in vBulletin 3.8.2:

I have control of my server so I can make changes, I have read other posts and can't really see what I need to change, below is my /etc/my.cnf file. Does it look ok or should I make any changes?
