controller not working live, but works on MAMP.

Hi guys,

I have a very weird problem. I built an application using codeigniter, and have just done a live testrun.

However, while all of my other controllers work without any issue, there is one that doesn't load (as in, it just loads a white page without errors). This controller works without problems on my local installation. This is the constructor and index (there are a bunch of other functions as well, but none of them work when called):

Code:

<?php
class Beheer extends Controller {
    function Beheer()
    {
        parent::Controller();    
        $this->load->library(array('Erkanaauth', 'session'));
        $this->load->helper('form');
    }
    
    function index()
    {
        $this->authorize();
        $data['productcats'] = $this->crud_model->getAll('productcat');  
        $this->load->view('beheer/beheerView', $data);
    }

I have tried doing this:

Code:

<?php
class Beheer extends Controller {
    function Beheer()
    {
        parent::Controller();    
    }
    
    function index()
    {
     echo "test";
    }

But that didn't work either. I am kind of dumbfounded as to what the problem could be.
I also tried running it without using .htaccess to rewrite the url (so with index.php in the url and no htaccess).

Any ideas as to what this could be?
