I upgraded my PHP and now it works.
I may have just fixed it..
I just un-ticked this box in the product page, inventory settings:
“Sold Individually: Enable this to only allow one of this item to be bought in a single order”
I’m not sure why that would fix it. But thought I’d post here in case anyone else has that problem.
It seems to still allow a customer to only buy one item in a single order, so I’m not sure if this is a bug? I do want to allow someone to order just one, and that is why I had that boxed checked. But, unchecking it seemed to resolve the issue I was having. 🙂
