I've got problems accessing your site or the past 2 weeks. I'm using recent Safari plus Ghostery (sort of an adblock, but I'm using it to disable facebook). I get the following errors whenever I try to acces either the forum or client area:

Code:
PHP Warning: session_start(): The session id is too long or contains illegal characters, valid characters are a-z, A-Z, 0-9 and '-,' in ..../includes/facebook/facebook.php on line 49

PHP Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at ..../includes/class_core.php:5802) in ..../includes/facebook/facebook.php on line 49

PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
Can you look into it?
