After upgrading our webshop www.veggfolie.no i now experience from time to time (annoyingly often) that completely different items gets added to the shopping cart.
I choose something, make the size/color choices and when i click to buy i can se that the shoppingcart sum is not correct. And when taking a look there is1-3 totally different items also added.
I have even seen items with custom options that customers must have made (names for print etc).
Has anyone experienced this before? Any tip on where to start?
