I'm having the exact same problem with JotForm. I have forms that started getting the same error when users went to the payment area to make their payment through PayPal. I tried the suggestion regarding changing/updating the business address but that didnt' work for me. I have some older forms that seem to work fine - but I have a hand full that no longer work. I can't begin to express my disappointment in the slow response I seem to get from support. I submit a question and it has taken as long as 3 hours to get a response. Beyond frustrated. Can anyone help me understand and fix this issue?
