Paypal integration not working

B"H

Whenever i try to testing the Paypal option by filling in the form, i get the following message (from Paypal): "Things don't appear to be working at the moment. Please try again later."

This seems like a duplicated post, I already assisted to you here: https://www.jotform.com/answers/1442496 

Please kindly avoid to open multiple threads for the same issue, having one thread only helps us to assist better and quickly. 

Thanks.
