body: <p>Facing an issue with theme roller in APEX 5.0 for a client's application steps performed are as follows.</p>
  
  <ol>
  <li><p>Logged in APEX and ran your application.</p></li>
  <li><p>Enter the credentials to run your application.</p></li>
  <li><p>The normal home Page has Blue colour side bar consistent with the Universal theme.</p></li>
  <li><p>Theme roller and selected the style as Vista (Copy) and set as current, at that time the colour in the home page changes(sea green) as expected.</p></li>
  <li><p>After exiting from the theme roller the home page changes to white colour (neither sea green nor blue).</p></li>
  <li><p>Checked the console message and got the following error message.</p></li>
  </ol>
