If you were browsing on our site before purchasing your membership, sometimes the web browser will retain that non-member status.
The problem will most likely be solved if you reload the page in question; that will force the page to refresh the settings associated with it.
In most browsers the command to reload a page is (in Windows) Control-R or (on Macs) Command-R. If you’re using a browser on a mobile device, swipe down on the page to reload it.
