Up until May 28th, I wasn't having any problems with Paypal Website Standard. Now whenever I place an order, the order status is stuck in pending. The order message says "order created through website", but the usual "PayPal IPN reported a payment" message no longer appears.
I've followed a lot of threads describing problems with IPN, but most of them are related to Workflow-ng not changing the order status. I checked out my recent logs and see that after May 28th, uc_paypal module no longer sends an "IPN transaction verified" message. I still continue to receive the "Receiving IPN at URL for order #" message though.
Does anyone have a clue why this may have stopped working?
