PayPal integration is not working

I keep getting an "invalid configuration" error when someone tries to make a payment through PayPal. I have spent hours and hours trying to correct this. Even called PayPal to see if it was something on their end. Can you please help get this set up and working? 

Can you please tell us which of your form have issue with PayPal payment integration. I checked the forms on your account but none were using PayPal payment integration.

I found that one of the form was using Square payment integration instead.

Base on the screenshot error you provided, this occurs if you did not enable "Digital Goods transactions" in your PayPal account but have enabled it in the form.

Set up your PayPal Business Account for Digital Goods
