Functions from external classes not working

How bout you replace the content of the file with something like

Code:

<?php

die('here we are');

and see if it works?

If you will see the output 'here we are' it's at least not a problem of not finding the file but something within the class.

Oh, btw: Does the file have a closing PHP-tag at the end? Don't think this is the problem, but may be - and CI recommends not using closing tags
