It appears we have been processing orders for your PayPal payments as recently as a few days ago, so that probably rules out a general issue with your PayPal integration settings (unless you've changed any of those settings in the last few days), but you may still find useful some of the troubleshooting tips on this help page:
If the affected payment is not in your E-junkie Transaction Log, that indicates either we never received IPN (Instant Payment Notification) from PayPal confirming completed payment for that transaction, or the IPN we did receive from PayPal referenced a payment recipient email that did not match the current PayPal Email setting in any seller's E-junkie Profile, so we could not determine which seller's product to process that order for.
The latter can sometimes happen if the seller happens to change their PayPal Email setting at our end after a buyer has taken their order to checkout but before PayPal completes that buyer's payment.
However, lately we have noticed an apparent spate of sporadic cases where PayPal sends us a completed-payment IPN only referencing the primary email for the seller's PayPal account, although the payment was originally sent to a different, secondary email linked to that account. We're gathering cases to bring this matter to PayPal's attention, so if you think this may be relevant to your issue, please email Support with any affected Transaction ID(s):
