Dear community,

The problem happens here:

https://wcfm.triplebit.com/product/advise2/

I'm a developer and I develop a marketplace. The customers get the following result after beying with Credit Card within Paypal:

 "something went wrong. Please try again or choose another payment source".

Any idea?

Thx
