title: Tried using white noise and got the following "error ImportError: No module named 'whitenoise.middleware' "
body: <p>I tried to follow the whitenoise instruction. I installed it from my requirements.txt the following are the versions I'm using</p>
  
  <pre><code>whitenoise==2.0.6
  Django==1.9.2
  </code></pre>
  
  <p>then I installed it in my settings.py middleware like the instructions say</p>
  
  <pre><code>'whitenoise.middleware.WhiteNoiseMiddleware',
  </code></pre>
  
  <p>this caused a system interrupt when I did this. When I went to local host I got the following error </p>
  
  <pre><code>A server error occurred.  Please contact the administrator.
  </code></pre>
  
  <p>When I googled I only saw one other intance of the problem I had. It was on github and they suggested 'Use the documentation on ReadTheDocs, github is where development happens and the docs there refer to the unreleased version.'</p>
  
  <p>How can I fix this? all guidance is welcome</p>
  
  <p>EDIT Traceback</p>
