I have a hidden product and somehow people are ordering it. It is set to visibility None. How is this possible?
Check to see if you have product link elevation activated on the product. When you edit the product, it's a check box on the upper right side of the first page. Also, you might check to see if you have category link elevation activated on ANY of that product's categories. Check the primary category, and any additional categories to which that product might belong. Product and category link elevation allow for you to give discrete access to hidden products or categories. While they may be hidden to all other users, if you have product or category link elevation activated, anyone who has the link to that product or category can access it. If category link elevation is activated on a category, it extends visibility to all the products within the category.
