I'm finding that shortcodes are remaining visible in membership.
As in, when not logged in, it hides things perfectly - http://exploringfoodandwine.com/ - the top post shows a bit saying "Sorry, you need to be a paid member to see this. Please register to view this content!"
However, when logged in, whilst it shows the paid content, it also shows [paid] and [/paid] round the content. Surely those should remain invisible?
