title: Umbraco throwing 404
body: <p>I have an umbraco 4 site that I have put a google sitemap onto.  This all works fine locally but on the live server I am getting an IIS 404 error (not the umbraco 404 error) - <a href="http://www.fmg.co.uk/fmg-corporate-sitemap/" rel="nofollow">see this link</a>.</p>
  
  <p>However if I preview the node it works fine</p>
  
  <p>I have googled why I would get a 404 and so far I have come up with the following causes which I have checked and can rule out as the cause:</p>
  
  <ul>
  <li>the template is not assigned</li>
  <li>there are multiple nodes with the same url</li>
  </ul>
  
  <p>Would anyone know what is causing this problem or how I could fix it?</p>
  
  <p><strong>Update</strong></p>
  
  <p>I have deleted the preview node now as I recreated the node in a different place and it worked.  Would still like any thoughts on why I would get a 404 though, just in case a similar thing happens in future</p>
