title: Template does not exist: 500.html
body: <p>I have created a template for the 500 HTTP error.</p>
  
  <p>I have inserted my template <code>500.html</code> in:</p>
  
  <ol>
  <li>/project/</li>
  <li>/project/templates/</li>
  <li>/python2.5/</li>
  <li>/python2.5/templates/</li>
  </ol>
  
  <p>but I always get this error:</p>
  
  <pre><code>TemplateDoesNotExist: 500.html
  </code></pre>
  
  <p>I get the same problem for an HTTP 404 error.</p>
  
  <p>Why?</p>
