About CodeIgniter_Ion_Auth.

[eluser]InterMedio[/eluser]
Hello.
I use code CodeIgniter_Ion_Auth and I need, if user logged in, then user redirect to viewsecretpage.php, if not - redirected to auth form.
And I created controller Secretpage:

Code:

<?php defined('BASEPATH') OR exit('No direct script access allowed');

if ( ! class_exists('Controller'))
{
class Secretpage extends CI_Controller {}
}

class Secretpage extends Controller {

function __construct()
{
  parent::__construct();
  $this->load->library('ion_auth');
  $this->load->library('encrypt');
  $this->load->library('session');
  $this->load->library('form_validation');
  $this->load->database();
  $this->load->helper('url');
    
}
function index() {
  if ( !$this->ion_auth->logged_in() )
  {
   redirect('auth/login', 'refresh');
  }
  else
  {
   $this->load->view('viewsecretpage');  
  }
}
}

and created view - viewsecretpage.php in folder views.
also I changed some code in method index() in file auth.php (Auth controller) to:

Code:

.....

function index()
{
  
  if (!$this->ion_auth->logged_in())
  {
   //redirect them to the login page
   redirect('auth/login', 'refresh');
  }
  elseif (!$this->ion_auth->is_admin())
  {
  

              /**************************  Here I have made changes.*******/

                         //redirect them to the home page because they must be an administrator to view this
   //redirect($this->config->item('base_url'), 'refresh');//previous
       redirect('secretpage/index', 'refresh');//I changed
              /*********************************************/




  
  }
  else
  {   ............

And When I authorize, codeigniter print error: 404 Page Not Found.
Why? Also I tried inserted just $this->load->view('viewsecretpage'); but same situation.
Please help me. Thanks.
