title: CodeIgniter 404 page
body: <p>When I enter a non existent url on my site it takes me to the 404 page that is specified by this in routes.php:</p>
  
  <pre><code>$route['404_override'] = 'page/not_found';
  </code></pre>
  
  <p>So the design of the page is as I have made it in the view not_found.php in the "page" directory.</p>
  
  <p>However if I use this function to manually enforce a 404:</p>
  
  <pre><code>show_404();
  </code></pre>
  
  <p>It takes me to the default CodeIgniter 404 page with no style:</p>
  
  <pre><code>404 Page Not Found
  
  The page you requested was not found.
  </code></pre>
  
  <p>How can I make it go to the same 404 page that I specified in the routes file?</p>
