title: CodeIgniter 2 not allowing multiple level subfolders for controllers
body: <p>As I read the <a href="http://ellislab.com/codeigniter/user_guide/general/controllers.html" rel="nofollow">doc</a>, controllers in CodeIgniter are supposed to support multiple level subfolders, but as far as I have tested, it is impossible to work after first a first level folder.</p>
  
  <p>By example:</p>
  
  <p><code>mysite.dev/</code> (index page, default controller home.php, works)</p>
  
  <p><code>mysite.dev/admin/</code> (admin section, in admin/home.php, works)</p>
  
  <p><code>mysite.dev/admin/manage/</code> (in admin/manage/home.php, do not work)</p>
  
  <p>I am trying to know why and how to make it work on multiple level sub folders? </p>
  
  <p>Thanks in advance!</p>
