title: Cannot get django-debug-toolbar to appear
body: <p>No matter what I do, I simply cannot get django-debug-toolbar to appear. I've tried everything suggested in <a href="https://stackoverflow.com/questions/10517765/django-debug-toolbar-not-showing-up">every answer on this question</a>. </p>
  
  <ul>
  <li>I have <code>DEBUG=True</code> in my settings</li>
  <li>I have <code>django.contrib.staticfiles</code> and <code>debug_toolbar</code> in <code>INSTALLED_APPS</code></li>
  <li>I have <code>'debug_toolbar.middleware.DebugToolbarMiddleware'</code> high up in <code>MIDDLEWARE_CLASSES</code></li>
  <li>I have <code>INTERNAL_IPS = ()</code> in my settings</li>
  <li>I tried adding <code>print("IP Address for debug-toolbar: " + request.META['REMOTE_ADDR'])</code> in a view, and it printed <code>IP Address for debug-toolbar: 127.0.0.1</code></li>
  <li>I have a closing <code>&lt;/body&gt;&lt;/html&gt;</code> in my template</li>
  <li>I have run <code>pip install django-debug-toolbar</code> in my virtualenv, without any issues</li>
  <li>I have run <code>python manage.py collectstatic</code> and there is a <code>debug_toolbar</code> directory in my static files</li>
  </ul>
  
  <p>When I run the app, I see no request in the console for any URLs containing django_debug_toolbar, so I suspect it's the application not being loaded. </p>
  
  <p>I don't see any failed requests in the developer console, either. </p>
  
  <p>I've read the <a href="http://django-debug-toolbar.readthedocs.org/en/latest/installation.html" rel="noreferrer">django-debug-toolbar installation docs</a> and am out of ideas.</p>
  
  <p>Does anyone have any suggestions for debugging? I'm running OSX and Django 1.7. The curious thing is that debug-toolbar WAS appearing just fine - I think I've made some tweak that caused it to vanish, but I don't know what. </p>
  
  <p>UPDATE: I've even tried adding this in my settings file, which is supposed to force the toolbar to appear: </p>
  
  <pre><code>def show_toolbar(request):
      return True
  SHOW_TOOLBAR_CALLBACK = show_toolbar
  </code></pre>
  
  <p>But it doesn't help. </p>
  
  <p>I've also tried throwing a deliberate exception in my view, so that I can check DEBUG is on and all the settings are as above. They are, and still no toolbar!</p>
  
  <p>UPDATE 2: When I set <code>INTERNAL_IPS=('127.0.0.1',)</code>, I start to see debug-toolbar requests in the console, but no toolbar on the page. </p>
  
  <p>And the following HTML appears in my page - so the toolbar is there, but it's not visible because it's got <code>display=none</code> set all over it:</p>
