Hi Stefan,

Thanks for the note! The first warning is caused by "safe mode" and the error reporting configuration on your server. The second one is caused by the first one.
I'll implement a check whether safe mode is enabled or not. You can quick & dirty "fix" it in your installation by replacing set_time_limit() by @set_time_limit() in includes/functions.inc.php (5 times; this will just ignore error messages).
