ISPCP and php.ini - Debian Wheezy

[Haros]

Sorry for the continuous posting. While everything seems to be working I have a problem only with one website. I get an error 500.

The apache default error log:
(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
Premature end of script headers: index.php

my suexec log seems to be ok:
