Hi Jim So this is now happening for all orders from PayPal? And it's the notification your receive from PayPal that has stopped, not the one from the store? If that's the case, did you inadvertently switch off the PayPal notification in your PayPal account?
Hi Jim If you're saying that it's the notifications from PayPal that have stopped then I don't think the settings that have to do with the shopping cart will have any bearing. Also, if you are using PayPal Checkout (as opposed to PayPal Standard) then IPNs are not used at all. Really, I think you need to take this up with PayPal as we don't control how PayPal send emails.
