title: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path
body: <p>I have gone through every other answer and cannot seem to get anything to work for me. I am following a tutorial and trying to push my <code>master</code> branch to heroku and get the error <code>You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path</code>. I am using Django 2.0 and python 3.6.3. The full traceback: </p>

  <p>I tried getting rid of the <code>if</code> statement to see if that was the problem but no luck. Looking for any advice. </p>
