O.K. I am confused. When you say, "I tried to change mySQL_PDO into mySQL", what do you mean by that?

You can't use the old MySQL driver, it has to be MySQL PDO.

It sounds like you error is in connecting to the database server. Turning on debugging in config file might help, but the login page won't show debug info (for security reasons).

Check your username, password and host to the database server. This is usually the problem.
