Which error is reported? (Actually, this is a question for a web developer forum rather than a Bugzilla bug report)
[04:58:08.313] auth is not defined @ http://127.0.0.1/:1
The line... location.href=\"./PHP_scripts/login.php?username=\"+username+\"&\"+password=\"+password; Why do you have to escape the double quote at the beginning? It does not look like a complete string for me...
Never mind. Please ignore my previous comment.
Closing as incomplete. If there is a ongoing problem please reopen and provide clear steps to reproduce.
