We have a force.com site and have recenecly changed our google analytics tracking code in the site settings - for some reason the pages (which are using the tag which should pull the analytics code in automatically) are still using the old analytics code. I can't find anything anywhere that suggests this would be cached, does anyone have any idea what would cause this?
