Magento Shipping (powered by Temando). This new feature provides integrated advanced multi-carrier shipping and fulfillment.
This is the new feature for the MCE 2.2.2
But after we upgrade this version, the checkout page can not be visited.
We totally understand the Magento requires more feature for the development.
But for the NEW feature, could you make it disable by default? and let us decide to use or not use it. ok?
