Just to let you know that this issue is now resolved.
It turned out to be some malicious code (trojan) that had somehow got into my eqdkp files. I deleted them all and re-uploaded fresh copies of every 0.6.4.0 file, and now everything works again

The problem I have now is : -
How can I reduce the width of the left menu column (ie. where the 'last fightlogs', 'menu', 'shoutbox' etc modules are)? I had a play around with some settings, and I managed to reduce the width of the column, but the text just got cut off. I need some kind of n00by beginners/idiots guide! :p
It's ok on the main page, but when you go to the "forum" tab, it really doesn't leave much space to display the Forum at all. This is especially true when people start to upload big pictures and screenshots which I am having real problems with. I've tried all sorts of phpBB3 tutorials and fixes, and I just can't seem to get them to either open in a new window, or resize in some way that doesn't send the entire topic off the right-hand side of the screen. Firefox seems to be the only browser that handles this well and resizes images well .... Internet Explorer and Chrome seem to make a total mess of things!!
Here is my site btw - Main logo is missing as I don't have the artwork on this PC at the mo
