So, your customer has tried to place an order and after entering their delivery address got this error?
Don't worry, nothing is broken. But it looks like you might have forgotten to set up your shipping rates or missed one of the delivery zones.
To make sure you have shipping rates that would cover all of your delivery zones, please follow this guideline when setting up the rates in your Shopify account.
If you are more than certain, that the shipping rates are set up correctly, yet your customers are still experiencing the same issue, please send us a Shopify collaborator access for [email protected] and notify our customer support team so we can check your account.
