I'm having this same issue, only with Cpanel. Any ideas? Everything looks correct...
Site error: the file /usr/local/cpanel/whostmgr/docroot/cgi/softaculous/enduser/main/functions.php requires the ionCube PHP Loader ioncube_loader_lin_5.2.so to be installed by the site administrator.
--edit--
php -m|grep ionCube
-RETURNS THE FOLLOWING:
ionCube Loader
the ionCube PHP Loader
