Hi!
I have also encountered this. It was working fine until now. When I select the Gear icon for a category within the shop > "Edit Category" window appears, the enable page button is grayed out - when I hover over the enable page button there is a "prohibition" sign or "do not" sign in red that appears. This is the same result on all my categories. I am not sure if that is defaulted or if that is a contributor to this concern??

I am not sure what to do, was there a fix that worked? I have not altered or edited any codes. I have only uploaded pictures and typed in descriptions/titles.
