I have had paypal emails about an IPN error on 3 of my stores over the weekend. My clients with this error are on VirtueMart, not Magento. I think Paypal must have changed something with the IPN method because there was a slew of people having issues with it. Paypal was creating non-existent IPN urls and sending them to customers post-transaction.
Not Magento. I think Paypal must have misrepresented incredible with the IPN method since there was a slew of people having issues with it. Paypal was creating non-existent IPN urls and sending them to customers post-transaction.
