I am trying to submit a sitemap for my mapped domain site to Google. I've tried pasting in ourblogname.wordpress.com/sitemap.xml. for an xml sitemap. It can't find the page. I've tried uploading a manually created xml file following Google's guidelines to a post and a page and then submitted those. Google says they are unsupported file types. HELP! Any ideas besides un-mapping my site (which I can't do until October) and hosting it with Go Daddy where my domain lives?
The blog I need help with is hungrynomadmaps.com.
