Check the gateway log for IPN Handshake Invalid

From time to time we get a PayPal problem. The payment is received, but there is a problem with the transaction with the error “IPN Handshake Invalid”.

Other errors are possible, but the hooks is not ready for them yet. Do you have suggestions for different kind of errors and payment gateways? Contact us or comment this post, we’ll be happy to improve it and make it more configurable!
