I successfully submitted sitemap.xml on the server.. but getting the
following error:
"We have successfully received your sitemap! However, we found some
URLs listed in your sitemap that we cannot accept. The list below is a
sampling of the URLs we could not accept, with links that explain the
type of error and how to correct it. "

and here is the URLs:
