Adverts still appearing as "Premium" user

If anybody else has this issue, you simply need to manually refresh the webpage after you've logged in, otherwise the adverts seem to keep appearing even when navigating to other site pages.

There was a time when ads never popped up for Premium members. I see the same thing consistently. I log in and voila, there's an ad at the bottom of the page. Premium members shouldn't need to refresh the page at all. One of the reasons I became a Premium member was to not have to deal with ads popping up.
