I am having issues with my Code Ignitor, in that I load my model the code fails, without leaving any trace.

I am attempting to load my model like so

```
<!--CONTROLLER-->
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Concierge extends Public_Controller {

public function submit()
{
    $this->load->model('Concierge_model');
}

```

My model is set up as below:

```
<!--MODEL-->
<?php

class Concierge_model extends CI_Model {

public function __construct()
{
    parent::__construct();
}

function saveRequest($action, $owner)
{
    $query = $this->db->query('select * from table');
    return $query;
}

```

Does anyone see what might be the issue that is causing my problem? I am using CodeIgnitor 2.1.2.
