After a failed update, I went back to my backups, but the Admin side of XOOPS has gone bang. Blank screens all over.

I was thinking of taking the tattered remains of my 2.0.13.0 database and trying to get a fresh copy of 2.2.2 working, with the information for my users, forums and xcgal running.

Anyone got any golden tips for doing this? I've not being very successful at getting even just the users in. I'm going to take a copy and update it, and copy the tables to a fresh install.
