In my Jigoshop site everything seems to be working fine except if a customer adds an item with "variations". I have an items that includes 4 variations and if any of those are added to the cart there is no option to check out when the customer clicks "check out". Everything else is available (log in, create user, shipping info, etc), but no "paypal" button. If I have other items in the cart with it you still can't check out. If there is just items without variations, then check can be completed as normal.
This item used to work no problems, but now does not. The item in question is this one: http://infectedarmory.com/product/mosfet-w-active-braking/
