[Solved] Getting firefox redirection error?

[eluser]riwakawd[/eluser]
When i set my config item to true config_item('system_maintenance') it redirects to URL but Firefox display error saying redirection error. I have attached error image

Redirects to URL OK but just unable to load page

Error:

Code:

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

MY_Controller.php

Code:

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

class MY_Controller extends MX_Controller {
  public function __construct() {
      parent::__construct();
     if(!config_item('system_installed')) redirect('install');
   }
}


class Catalog_Controller extends MY_Controller {
public function __construct() {
      parent::__construct();
      if(config_item('system_maintenance')) redirect('maintenance');
   }
}

class Admin_Controller extends MY_Controller {
public function __construct() {
      parent::__construct();
      if(!config_item('system_installed')) redirect('install');
   }
}

Config.php

$config['system_installed'] = TRUE;

$config['system_maintenance'] = TRUE;

modules/catalog/common/maintenance.php

Code:

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

class Maintenance extends Catalog_Controller {

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

public function index() {
  $this->load->model('admin/users_model');  
  if($this->users_model->isLogged()) {
   $this->info();
  }
}

   public function info() {
      $this->lang->load('catalog/maintenance', 'english');
      $data['title'] = $this->lang->line('heading_title');  
      $data['heading_title'] = $this->lang->line('heading_title');          
      $data['breadcrumbs'] = array();
      $data['breadcrumbs'][] = array(
         'text' => $this->lang->line('text_maintenance'),
  'href' => site_url('catalog/common/maintenance')
      );
    $this->load->view('theme/default/template/common/maintenance', $data);

After spending few hours on it I have fixed issue seem to work now since not have spaces on second class in my controller like so

Code:

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

class MY_Controller extends MX_Controller {
  public function __construct() {
      parent::__construct();
      if(!config_item('system_installed')) redirect('install');
   }
}

class Controller extends MY_Controller { // Working Now With No Underline
   public function __construct() {
      parent::__construct();
      if($this->config->item('system_maintenance') == TRUE) {
         redirect('maintenance');
      }
   }
}
