When customers try to pay with paypal, they get the error messages of
[Payment processing failed
Odoo Server Error]
and
[Payment processing failed
PayPal: The communication with the API failed. Details:]
I've tried every known solution as instructed on the website, and even on the forums - including manually pasting the webhook and setting up the paypal.
Can anyone help me? I am looking to start selling by next week and this is the only obstacle remaining.
