Why are there some invalid fields in the billing address?
If a buyer sees the message: the “Zip Code/Country” field of your billing address is invalid when choosing the payment method:
- In the Standard payment section, make sure that Propose FacilyPay Oney is set to No.
- Make sure that the FacilyPay Oney payment submodule is not enabled.
The activation of FacilyPay Oney creates restrictions on the address, phone number, zip code, country code, etc. These restrictions will block buyers in foreign countries.
