Paypal and Stripe payments not working.

Paypal and Stripe payments not working.

Hello,
Recently the paypal and stripe payments option on the zoho forms has stopped working. The payment platform doesn't process the payment after the form is submitted. I have tried removing it and then redoing the payment section and making sure all the account information is correct with no luck. Please see the link below. Please advise how to resolve this issue. Thank you.
