Your cart has been updated and the items you added can’t be shipped to your address

Hello, I have been trying to figure out this issue for a very long time now and cannot seem to figure it out. I am currently testing my website and when I type in any address it says “Your cart has been updated and the items you added can’t be shipped to your address. Remove the items to complete your order.” I am using SPOD as my distributor and was wondering if anybody know how to fix this problem? Thank you!

Is your SETTINGS > SHIPPING set up correctly for the country you entered as the shipping address?

NOTE: It says “Then, you simply have to use a name that our system will recognize. Those would be Standard, Premium, or Express.”
