Faced the problem that the specified link in the Paypal button (/ payment / paypal / dpn) does not return data on the transaction. Because of this, there is no redirect to the desired page and the order basket is not cleaned.
I set up Paypal according to the instructions ( https://www.odoo.com/documentation/user/10.0/ecommerce/shopper_experience/paypal.html ).
Odoo 8 with the latest changes (added PDT here is the link https://github.com/odoo/odoo/blob/8.0/addons/payment_paypal/controllers/main.py ). IPN is working.
This problem occurs in the sandbox and at Paypal production.
Maybe I did not set something up ...
Someone can suggest a solution.
Thank you in advance.
