Google is telling me this:
We've detected that you submitted your Sitemap using a URL path that includes the www prefix (for instance, http://www.example.com/sitemap.xml). However, the URLs listed inside your Sitemap don't use the www prefix (for instance, http://example.com/myfile.htm).
Can anyone help me understand what I can change in order for my sitemap.xml file to contain urls with the www. prefix?
