I recently upgraded both WordPress and the eshop plugin and have encountered an error when trying to set my shipping rates in eshop. I go to the shipping tab and select shipping Method, zones, zone number and default zone. When trying to select defauly country, the drop down selection does not load, only says "Please Select". Upon pressing "Update Shipping Rate Calculation", nothing happens. The Shipping Classes and Zones table is the same (only headers). Also, when I select the "Countries" or the "State/County/Province" tabs up top, the shipping zones section is blank. If i fill out the code, country and zone, and press update, nothing happens.
I assume because of this, when an item is added to the shopping cart on my website, when trying to checkout, i get and error: "Error, please contact site owner."
