    We are receiving an error when submitting a form with PayPal payment processing tool

    Asked by LGHmarathon on July 29, 2015 at 04:01 PM

    I created a form and when I tested it, I received an error message after I click the submit paypal button. I spoke with Paypal and they've requested that I speak to JotForm and that the error could be on your end.

    Seems like you have embedded the form using the SSL (Secure version) and since the site itself it's not secure, but on the standard HTTP protocol, then it's giving you this error.
