Fantastico problems

I) Fantastico is not installed at the default location
/usr/local/cpanel/3rdparty/fantastico. Either move the
Fantastico directory from it's current location to
/usr/local/cpanel/3rdparty/fantastico OR enable
ioncube loaders in WHM -> Tweak settings.

II)Internal Server Error

Premature end of script headers: /usr/local/cpanel/whostmgr/docroot/cgi/addon_fantastico.cgi: Please check /usr/local/cpanel/logs/error_log for the exact error.

======================

solution: The problem is related to perl

cd /usr/local/bin/ ;
mv perl perl.old ;
ln -s /usr/bin/perl ;
