If the eBay account has been upgraded to the new Managed Payments and eBay are returning the above error for items with Global Shipping Program enabled, you can either contact eBay and opt out of Managed Payments for the time being since the Global Shipping Program is not supported yet by the new managed payments experience or as outlined in the error, to disable it and list the item temporarily until it would be supported and you can take a look at this eBay page as it goes into further detail.
