title: Unable to locate the model you have specified - CodeIgniter Issue
body: <p>I'm getting an unable to locate model error.</p>
  
  <pre><code>$this-&gt;load-&gt;model('1/Gift_model');
  </code></pre>
  
  <p>My model file name is <strong>gift_model.php</strong> within /models/1/.</p>
  
  <p>I declare the model the following way.</p>
  
  <pre><code>class Gift_model extends CI_Model {
  </code></pre>
  
  <p>According to CodeIgniter's documentation I'm doing it the correct way. Any suggestions? I have 5 other models named exactly the same way and they're all loading fine.</p>
