I `svn up`ped the Verbatim Alpha instance of Pootle and needless to say the database format apparently changed drastically since we last did that. I have yet to find documentation on how to update Pootle's DB without losing data, so this is the bug for that. If worse comes to worst, I'll need to regenerate an empty DB and cherry-pick data from the broken DB to somehow import into the new one. :(
I recreated a blank DB, then created the AMO project again. It came back and seems to work -- I dumped the old sqlite database to see what useful data it contained, but there were no user rights in there, so I call this one closed for now.
User rights are pre-sqlite. There is a mysql database on there that holds the rights.
