Hello: I use Google Apps, and I use custom web address http://www.dayabook.com for my Google App webpages instead of default one http://www.dayabook.com-a.googlepages.com, Google page creator automatically generates a sitemap for the site, both under http://www.dayabook.com/sitemap.xml or http://www.dayabook.com-a.googlepages.com/sitemap.xml are same thing. but when I tried to submit sitemap to Google Webmaster Tools, I got "URL not allowed" error for the custom web address, while it's OK for the default web address, because all the urls in sitemap.xml are something like this: http://www.dayabook.com-a.googlepages.com/a-foolish-man-buys-his-shoes.html So Google thinks those are under different domains, and doesn't accepted. How can I fix it? Any help will be appreciated.
