Google shows my sitemap has HTML forfait and won't accept it

[crocu]

Hello

I'm using Joomla 2.5.8
My site is hosted by servhome.org, my site is actually like this :
http://myownname.servhome.org, i also own 'www.myownname.fr' domain name that is redirected to the myname.servhome.org

Actually when Xmap generates the sitemap of my site it provides me a link pointing to http://myownname.servhome.org
The problem is Google does not accept my site map, i get a message telling that sitemap is in HTML format.
I'm sure to provide to Google the XML link given by XMAP.

How should i fix this issue ?
I really need Google to accept my site map.

Many thanks for your help,

I'm having the same issue.

I've submitted the xml url from xmap but Google Webmaster tools is giving me an error saying that it's html formatted.

help?
