Hi,
My site has already been verified and also marked as public. But as stated in Google [ "Once you have verified your site with Google Webmaster tools, Google Sites will auto-generate a sitemap xml file. Your sitemap will be generated at:system/feeds/sitemap], I am not able to find the sitemap generation in my site <snip/>. Because of that I am not able to submit the sitemap at Google webmaster tool. Kindly help me in this regard.
Specify the cms you using. If you cant find the sitemap in your URL/sitemap.xml there is no sitemap in your website. create and upload sitemap and just paste the URL in webmaster sitemap uploader.
