codeigniter - Query Strings with Code Igniter -

i'm trying setup codeigniter (v2.1.4) query strings , having problems passing variables. pages work when controller_trigger , function_trigger passed:

example.org/?c=page&m=index 

but when try pass variable:

example.org/?c=page&m=view&id=1 

the script throws 'missing argument' , 'undefined variable' errors.

in 'application/config/config.php' i've set:

$config['enable_query_strings'] = true; 

in 'application/config/routes.php' have:

$route['default_controller'] = "page"; 

and controller looks like:

<?php  class page extends ci_controller {      public function __construct()     {         parent::__construct();         $this->load->model('page_model');     }      public function index()     {         $data['title'] = 'page title';          $this->load->view('templates/header', $data);         $this->load->view('page/page_index', $data);         $this->load->view('templates/footer');     }      public function view($id)     {         $data['title'] = 'id page title';          $data['page_item'] = $this->page_model->get_page($id);          $this->load->view('templates/header', $data);         $this->load->view('page/page_view', $data);         $this->load->view('templates/footer');     }  } 

does know i've missed?

any appreciated

in config.php change:

$config['allow_get_array']      = true;    #example.com?who=me&what=something&where=here
