[update]

found the problem, a colleague had made a MY_Controller.php, which included a _remap() function. had to change the following in the _remap() method

Code:

//next line does not work for controllers in sub-folders
//call_user_func_array(array($this, $method), array_slice($this->uri->segment_array(),2));
call_user_func_array(array($this, $method), array_slice($this->uri->rsegments,2));
