title: "is_logged_in" templatetag does not render
body: <p>for some reason, templatetags do not render in templates for django admin.</p>
  
  <p>with this snippet from:
  <a href="http://docs.djangoproject.com/en/dev/ref/templates/api/?from=olddocs#shortcut-for-simple-tags" rel="nofollow noreferrer">http://docs.djangoproject.com/en/dev/ref/templates/api/?from=olddocs#shortcut-for-simple-tags</a></p>
  
  <pre><code>{% if is_logged_in %}Thanks for logging in!{% else %}Please log in.{% endif %}
  </code></pre>
  
  <p>when placed in admin index.html, if a user is logged in, it shows "Please log in"</p>
  
  <p>same with templatetags, can not get any app ones to show, do anything. there is no error/they do not get processed either </p>
