can anyone help... ps.. i already filled my config.inc.php file dunno whats getting wrong with it!

It's saying that the database information in your config.inc.php file is incorrect.

I'm getting similar:

Is this a problem with MY Sql or how I've set up the DB?

Either the database information you have provided in the config.inc.php file is incorrect or you haven't given that user access to the guestbooks database.
