Re: Unsupported file format

Is it: http://www.millionserved.com/sitemap.xml ?

Have you looked at the URL with a browser? It doesn't work :-) -
perhaps something on your server is trying to process the xml file as
some kind of executable / script. I am just guessing, but I think it
could be caused by something in your htaccess trying to rewrite that
URL into something it isn't.
