Hi I have gravity forms V2.4.8 with PayPal Standard add-on V3.1.1 and since April 21, I am noticing that Gravity form fails to process Paypal IPNs and shows all completed payments as “Processing”. As a result, our donors cannot get any notification.
I checked gravity form Paypal log and it shows the following message:

It seems that Gravity form is not being able to parse the IPN custom field. But when I check the Pyapal IPN fields, I do see the “custom” field.

Any help in this regard?
