Dear Christian Lewin,

due to upgrade of PHP 5.2 -> 5.3.1 some fixes were necessary and login should work now. By the way in PHP 5.3.1 are some changes and depreciated functions that might cause warnings in CHIP. When I have time I'll do some adjustments but until PHP 5.3.0 CHIP is running sweetly.

Kind regards,
