Hello,
on my chackout module, when the customer have to put his adress, in the Country List there ist no Cuba, why?
Do you have shipping rates set up for Cuba? You can check this in Settings/Shipping and Delivery.
If you’re not sure where to start, you’ll need to make sure Cuba is including in one of your shipping zones, or you can create a new shipping zone. Once you have completed this, make sure you have shipping rates set up for that zone. Let me know how this goes!
