Well if your going to make a game, dont use a free server, I'd honestly suggest getting a hosting package with w3, and then getting peter to connect them.
Oh sorry, if your soo good at PHP, surley you would have fixed it. Right?
Im telling you, if your using W3theory, then you need a password, I know you havent got one.
This fact you know is wrong. You get that error because the username annd password have been denied. Are you sure there isnt a space after the password or the username for cpanel actually has _1 in it?
Its nothing to do with localhost, as the user is denied..
