 * i had the same problem but upgrading the google sitemap plugin helped. One would
   expect to be notified of outdated plugins with 2.3 now but that wasn’t the case
   here. get the lastest version from [here](http://www.arnebrachhold.de/projects/wordpress-plugins/google-xml-sitemaps-generator/#P18DL).
 * Btw, the stats plugin notified me of possible upgrades so that is working fine.
   Proly the sitemap plugin hasn’t made it to the plugin db yet.

 * Yah, I found that I had Ultimate Tag Warrior installed, I guess I should have
   known that.
 * Thank You Very Much.
