So, tried to update in February to 3.0.7. Didn't work out...forums hosed. But I always back up the DB before updates, so I'm safe that way.
Finally got around to fixing this today. I have new domain so I tried it there first but because the paths are different I get locked out. So, back to here. Reverted to 3.0.4. Whole bunch of uploads and deletes in between, but now it is back up.
As of this time forum registration is disabled due to amount of spam accounts I get registering here.
