After upgrading to WordPress 2.01 the wp-shortstat plugin doesn’t work anymore. A google session later I found the reason for this problem in http://wordpress.org/support/topic/34905/page/2. The Goolge Sitemap plugin includes some WordPress admin functions and now wp-shortstat always thinks, you are admin and does not count any page. The suggested solution was to fix the sitemap plugin, but I think this plugin behaves correctly. So I fixed wp-shortstat the way that it does not test for admin functions anymore.
Meanwhile there are a couple of changes made to the plugin. Please send me your patches, if you want them included.
