title: Magento showing top menu twice
body: <p>Magento is showing the top (categories) menu twice after upgrade, see screenshot.</p>
  
  <p>It seems to me that the <code>top.phtml</code> is being executed twice by the line <code>&lt;?php echo $this-&gt;getChildHtml('topMenu') ?&gt;</code> in the file <code>header.phtml</code>. </p>
  
  <p>I have tried switching to the default code ( ie from the base/default theme) for each of these files but I get the same result. I have also checked the backend admin and when I pick a category and select 'NO' from <code>Include in Navigation Menu</code> the category disappears from BOTH iterations of the menu. </p>
  
  <p>Can anyone suggest a possible solution or course of action.</p>

  <p><strong>EDIT:</strong> I have discovered that setting <strong>system>config>design>themes>layout</strong> to the original ( downloaded ) theme as opposed to my own makes the problem go away, however I have layout mods I need to keep so I still need to isolate the problem</p>
