You really should start your own thread if you need help. It's too difficult to follow two different users with two different problems in one thread. Your error is spelled out - your user 'root' doesn't have access to get to your database. So, your config.php file is probably wrong. If you continue to have problems, make your own thread so we can better help you.

Moved posts to a new thread :).

You have edited your config.php file incorrectly, as Lynne has said.
