Hello, we have no idea what the problem of this is: Exactly at 00.00 AM/PM tonight our PSA Server 7.5.3 fresh installed last saturday, has reconfigured all clients with mssql databases and their rights to another user. So the first client wrote us tonight, he canÂ´t login in enterprise manager to his database with these error: Error: Server user 'uniteddb' is not a valid user in database 'maxxaccs'. Source: .Net SqlClient Data Provider That is not really funny, because user uniteddb has no database called maxxaccs in his account ! These database is from another client on this machine. So what the hell has Plesk doing? We wrote the 9! Ticket (Support) and we got a fix for 24 hours. After that time, the same comes again! So what is wrong here?
