In some of the sites in our single hosting application instance the Google sitemaps do not have any <url> entries, even though these sites have many nodes/documents, all of them published.
All sites have the CMS.Root document type assigned (by default) and the transformation CMS.Root.GoogleSiteMap is present and not changed from the default transformation as it was installed. There are no error messages, just an empty <urlset>.
Example of an empty sitemapExample of a sitemap missing documents (does not contain all documents in the site).
As you can see from the url, we changed the global setting
Google sitemap url from googlesitemap.xml to googlesitemap.
aspx.
Any idea what could be the cause of this problem?
