Hi All, Word of warning (and glad I did my backups first). I just upgraded from 2.2.6 to 2.2.7, and the entire contents of the ispconfig mysql database (all tables) were deleted. At the end of the upgrade, I got the message: All prerequisites are fulfilled. Here we go... Connected successfully to db ispconfig and then a bunch of php mysql_fetch_array(): supplied argument is not a valid MySQL result resource (because the tables were missing). I restored the mysql ispconfig db, and everything was fine again. Just to be safe, I re-ran the install against the existing 2.2.7 install, and everything went fine. So, I have no idea why/how that happened, but do your backups.
