This is not the end of the world, because the database seems intact, so I am hoping one of the good folks at phpBB will tell me how to get it connected to an installation and all will be well, but the board is down until then. I'm really sorry. If people want a temporary place to play till then, I can open up http://www.antagonia.net/antic_fables for you all. I think most of you have usernames there anyway.
Once again, my apologies. I have never had anything like this happen before!
ETA: 6 am-- problem solved; I figured out how to fix it on the back end. Apparently our board style is incompatible with the new version of phpBB. So you will notice it is not pretty right now and some of the hand-coding, like the date feature I did is no longer in there. HOWEVER, the add user feature somehow managed to survive. I'll add that back in as soon as I have a chance. But now I need to sleep. And we DO have an updated board.
