We've just updated our store and on 4.4.4 (I think it was) we had a hidden category, but we could link directly to products for people to buy (think things like tickets that only certain clients are invited to. The problem is though, since updating, when you view a product in a hidden file now, it is just a plain blank page. Anyone know how to sort it? It doesn't make much sense seeing as the items show up in search results, but then when you click them, it's just blank?! Any help appreciated! Many thanks
