I have an error after a recent update to Magento 220.127.116.11 when I try to save a product in a specific storeview.
It seems to me the group-price is set correctly like this. Anyway, before the upgrade it worked. The solution could be to add the group-price in every website separately, but that would be a lot of work.
Is this common behaviour or a bug? Anyone experienced the same or knows a fix?
