Express Checkout returns to shopping_cart.php?error_message=

[toiletrulle 0]

Topic pretty much says all.

I installed express checkout module, and tried it in both live and sandbox mode. The API test in the admin-module worked correctly, but whenever i go and press the "Express Checkout" button in the shop, it just returns me to the shopping cart - apparently with an error, but no errormessage: "/shopping_cart.php?error_message="

 

Anyone seen this before?

You need to collect request and response details to look as to what went wrong.

I got the same problem.

After upgrading from 2.3.3.4 to 2.3.4 and replacing the paypal express files, the same problem occur.

 

How can I check what the error is?

Please adivce.
