It looks like after updating our site to WordPress 4.96 and updating to PHP 7.1, that the cart function is no longer working. When you go to open the cart, it says, “It looks like you are attempting to refresh a page after completing your registration or your cart is empty. Please go to the events page and try again.”
I reverted to PHP 7.0, which restored functionality to the cart. Any thoughts on what the issue might be?
