XF 1.3 MYSQL errors

Got a message from one of my forum members today to say theres some strange code showing instead of the forum. Logged in & sure enough it was showing some errors. I know next to nothing about MYSQL but the forum was working fine last night when I did my bot check & log empty. I thought it was about time to upgrade to 1.3.3 from 1.2.2 (I know I should have done it sooner) thinking the upgrade would overwrite any files that were causing problems but when I go to complete the install process, after I go to the install directory & enter my log in details I get the code below showing instead of completing the install.

Server Error

Can anyone shed any light on this?

We have had numerous reports of this today.
