I have migrated from Magento 1.9.2.x to Magento 2.2.2 but when I click on the add to cart button, it gives this message:
We can't add this item to your shopping cart right now.

You can try to disable third party plugins to check is it any conflict. First try to disable this one responsible for cart.
