CodeIgniter extending file causes http 500

If I extend below file OR just autoload it in autoload.php all I get is http 500 and sometimes empty output. MYControllerInterface.php is located under application/libraries .

I've chmod'ed the whole directory (recursivly) to 0777. I've created a .htaccess with RewriteEngine On and Off in the root directory.

I've commented out everything from { to } in MYcontrollerInterface...

I've tried removed the ending ?>

I've checked that mod_rewrite is enabled in php config... This is so mysterious!

<?php 
class MYcontrollerInterface extends CI_Controller {
    public function __construct() {
        parent::__construct();
        //$this->load->helper('url');
    }   

    function build_page($main_content_view, $data) {
        /*
        $this->load->view('header', $data);    
        //$this->load->view('content', $data);      
        //$this->load->view($main_content_view, $data, true);
        $this->load->view('footer', $data);   
        */      
        echo 'apa';
    }   
}

/* End of file MycontrollerInterface.php */
/* Location: ./application/controllers/MYcontrollerInterface.php */
?>

If you are extending a controller (which is a core class) it needs to go in /application/core.

Also check your prefix, the CI2 standard is MY_ (check your $config['subclass_prefix'] at line 109).

UPDATE An extended controller must be called MY_Controller (as per the loader class).

You would then use it like...

class foo extends MY_Controller {
    function __construct() {
        parent::construct();
    }
}
