Cannot Fix Internal Server Error 500

[sci2tech]

Possible cause:
php version <=5.2.0 (default for etch. Solution update php)
Mismatch between associated uid/gid for script, containing folder or /var/www/fcgi/domain.tld folder or content. Solution: correct uid/gid.
If limited resources or script take time to execute, increase for fcgid IPCConnectTimeout value (in /etc/apache2/mods-available/fcgid_ispcp.conf). Try switch to ispcp_fastcgi/ispcp_fcgid and see if problem persist.
Test if your configuration file template against trunk (maybe problem was corrected).
