We are a US based company, but do sell internationally. Our US orders go through without any hassle, however our international orders will NEVER go through. We have enabled each applicable country and assigned shipping for the countries that we ship to (mostly the UK, Ireland, Germany and Portugal). When these customers try to check out, they receive the message: (You have selected an invalid state/province and country shipping address combination, or no shipping methods were found for your shipping address destination. Please contact us for assistance!).
Is there another field somewhere that needs to be changed in order for this to work?
