I’m sooo clueless, but 4flush helped me get back up and running, then my hosting guy helped me add a patch. The redirect on my forum was just added into a forum post. Second time around, I learned to update my mySQL database..
I’m using IPB though ..
PS .. it royally sucked, and was frustrating as hell.. and felt like the end of the world at the time 
.. sorry it happened, seems to be happening rather frequently lately.
