Can't update cart quantity...
For some reason, I can no longer update the quantity of a product on the view cart page...
Possibly related (but maybe not), when I choose to "sum the quantity" when adding the same item to the cart, it will not update it.
Any ideas on where I should look?
UPDATE! I found the problem and fixed it. I had updated the options to be unique (so someone could add the same item with different options to the cart) and the newly generated eCart_PHP file was the culprit. I found the code that made the options field "unique" and moved that over to the backup I had and everything works fine now.
I suspect I am working with a much older copy of eCart on that site than I have installed... may or may not be the reason.
