title: Simple Code Igniter error...silent failure on load->model
body: <p>Sorry for the stupid question, but this is driving me crazy...</p>
  
  <p>I have test_framework.php as follows:</p>
  
  <pre><code>&lt;?php
  
    class Test_framework extends CI_Controller{
  
      function display_test(){
        echo "loading model...";
        $this -&gt; load -&gt; model('test_model');
        echo "model loaded...";
      }
    }
  ?&gt;
  </code></pre>
  
  <p>and test_model.php as follows: </p>
  
  <pre><code>&lt;?php
  
  class Test_model extends Model {
  
    function get_all(){
  
      $q = $this -&gt; db -&gt; query("SELECT * FROM users");
  
      foreach($q -&gt; result() as $row)
      {
          $data[] = $row;
      }
      return $data;
    }
  
  } 
  
  ?&gt;    
  </code></pre>
  
  <p>When I go to my index.php/test_framework/display_test, I see "loading model..." but never "model loaded...", and there are no errors (just a blank white page).  What could be happening wrong here??</p>
