What should I do when I receive the error message "PAYER_ENABLE_STATUS_FORBID"?

The error is caused by the fact that the buyer's Alipay account is deactivated and the real-name verification information cannot be sent to the customs. It is recommended that you contact and refund your buyer. You can also wait for the buyer's Alipay account being activated and send the real-name verification information again to the customs.
