title: Sitemap is HTML - but it's supposed to be XML
body: <p>I have a small web application made with cakephp, and I am trying to submit its <code>sitemap.xml</code> to Google Webmaster Tools. This is the sitemap's address: <a href="http://gomme.gommarolo.org/sitemap.xml" rel="nofollow">http://gomme.gommarolo.org/sitemap.xml</a></p>
  
  <p>The problem is, when I submit that address, google tells me that the sitemap is in HTML format, thus suggesting me to use another format.</p>
  
  <p>The content of that page, itself, looks like a proper XML file and even chrome says that its content type is application/xml.</p>
  
  <p>What's wrong with that sitemap?</p>
