undefined variable level error - help

[horseplop]

Now this message appears when trying to access our forum:

8: Undefined variable: level
File: /home/horseplo/public_html/forum/Sources/QueryString.php
Line: 369

Any help would be appreciated.

I was able to make a repair to the forum by going into the WHM , SQL, then finding the error log which must have been stuffed.  I emptied it from there.  I usually empty it from the Admin panel on the forum, but I couldn't get there. Thanks to everyone at SMF forums for the help and great suggestions. I probably will need them in the future as well.
