Are you using a plugin? If you have them hardcoded there is an explanation here. http://www.codefap.com/2013/05/disable-adsense-ads-to-logged-in-wordpress-users/ hope that helps, Nigel
Just found a plugin as well. Which is likely doing the same thing. http://geeklad.com/wordpress-plugin-to-remove-google-adsense-and-google-analytics Nigel
You can do it without a plugin Michael. All you need to do is use the is_user_logged_in() snippet and a if function around the ad block.
