W bazie danych

[weishimi]

We were able to connect to the database server (which means your username and password is okay) but not able to select the root database.

Are you sure it exists?
Does the user db50001 have permission to use the root database?
On some systems the name of your database is prefixed with your username, so it would be like username_root. Could that be the problem?

Nie trzeba ustawić uprawnienia? Lub ustawić problem?
