title: admin module css is not working in prestashop 1.6
body: <p>The admin tab for (<a href="http://www.mkehome.com" rel="nofollow">www.mkehome.com</a>) module <code>css</code> is not working. When I click on <strong>MODULES</strong>, I get no css with result page. The controller is not calling the css for admin module UI. When I go to update from the list of updates needed, I still get no css with result page.</p>
  
  <p>I have all the other UI's are working just fine. </p>
  
  <p>The Hover over (JS) on <code>topmenublock</code> on <code>homepage</code> also stop working.</p>
  
  <p>Any Idea?</p>
