[Plugin: Google XML Sitemaps] Google webmaster tools cannot download my sitemap

Hi.

I recently installed the Google XML Sitemaps plugin and it seems to be working correctly. Since my website still cannot be found through a Google search, I went to Google Webmaster Tools to provide my sitemap.

However, the sitemap download on Google has failed multiple times. The only information I get is:

“Error: The last attempt at downloading the Sitemap failed. The details below are representative of the last successful download.”

Google Webmaster Tools also says “No data available” for search queries, links to your site, crawl errors and keywords. For URLs in web index, it only says “–“.

I am using FatCow as my hosting service, FYI.

Any help is GREATLY appreciated! Thanks so much.
