These is how I came across this error:
From admin when I go to Orders -> click on any order -> when opened, it has EDIT option -> its gonna alert you that its gonna be modified and create a new order -> proceed -> under Price u have “ Custom Price* “ -> click on it and change it from 1 cent to like 1 dollar -> click on update items and Qty -> when u wanna submit order its gonna throw and error that u gotta pick shipping method.
Whereas, there are no shipping methods listed here. But we do have configured free shipping method on the site which is working perfectly in frontend.
Any idea?
