Even when I try to rebuild it manually I get this "The content of your sitemap didn't change since the last time so the files were not written and no search engine was pinged." This started happening when I upgraded from B7 to the new b10 version. I am running WP 2.2.2 ... I have even gone as far as to delete the site map and create blank files. Google Site Map generator comes back and says nothing has changed, even though I have created a couple of new posts. Please help.
