Mokka mit Schlag is borked at the moment. I think I know what went wrong with the upgrade, and I'm working on fixing it. In brief, the WordPress user did not have permissions to create and drop tables. This is indicative of a bug in WordPress--it does not verify that it has the necessary permissions before attempting to upgrade, nor does it notice that the upgrade has failed and perform a rollback. However the host (Pair Networks) has not been quickly responsive, so I'm not sure how long it will take; and I don't have the root database access necessary to repair the problem, so it may take a little while.
