title: Spacemacs powerline separator change not working
body: <p>I am trying to customize the powerline separator style for Spacemacs. I added the following code to my <code>.spacemacs</code> file, as section <code>11.1.5.5</code> of the <a href="http://spacemacs.org/doc/DOCUMENTATION.html#orgheadline76" rel="nofollow">docs</a> say to do.</p>
  
  <pre><code>(setq powerline-default-separator 'bar)
  </code></pre>
  
  <p>However, nothing is changing in my UI. I tried reloading via <code>SPC f e R</code> and restarting Spacemacs. Am I doing something wrong?</p>
