PayPal Checkout integration not working in Live Mode

So I integrated a form with Paypal and got it working, multiple times with the sandbox. Then switched to live and got the following error on submitting the form data:

Bad request (/payment-paypal-createOrder) - Payee account specified is invalid. Please check the `payee.email_address` or `payee.merchant_id` specified and try again. Ensure that either `payee.merchant_id` or `payee.email_address` is specified.

Switched back to the sandbox and am getting the same error. Any ideas?

Thanks,

Dan

I assume that the issue is related to your PayPal Donation Form. You posted your comment on our PayPal Checkout guide, but this form is integrated with PayPal Business. Please re-connect your form with PayPal Business and test it again.
