title: changed default_controller gives 404 codeigniter
body: <p>I am using codeigniter 2.1.2, WAMP, im just learning it and encountered a problem.
  all i did was following
  -> created a view "home.php" with some text in it.
  -> created a controller "homecontroller.php" as follows:</p>
  
  <pre><code>&lt;?php 
  
  class homecontroller extends CI_Controller{
  
      function iloadhomepage(){
          $this-&gt;load-&gt;view('home');
      }
  }
  </code></pre>
  
  <p>up till here it works fine when i run</p>
  
  <pre><code>"http://localhost/CodeIgniterTut/index.php/homecontroller/iloadhomepage"
  </code></pre>
  
  <p>next I changed the default controller in "routes.php" (in config) to </p>
  
  <pre><code>$route['default_controller'] = "homecontroller";
  </code></pre>
  
  <p>so that when i run "http://localhost/CodeIgniterTut/index.php" i would get my "home.php"
  but rather im getting a 404 error, am i doing a mistake anywhere? please help</p>
