I have a little problem with my project. The autoloader couldn't find my Acl model. The models folder is in the include path as you can se underneath. I try to load it with $acl = new Acl(); and the file is located in the models folder, with the name Acl.php. What could be the problem?

You can find my repository here: Dahliz91's Impleo-CMS at 1.0 - GitHub

The Include_path:
/var/www/domains/nightly.impleocms.se/impleo/libraries:/var/www/domains/nightly.impleocms.se/impleo/models:.:/usr/share/php:/usr/share/pear
