I'm getting that error whenever I try to order something from my clients site at https://store.brothersatwarmovie.com/ on ZC 1.3.9h. I'm not using any zones, and just 2.99 flat rate shipping. So this shouldn't be appearing. So why is it and what's the fix?
I currently have per item shipping set at 2.99 per item, Enable Item Shipping set to false, no handling fee, Tax Basis is Shipping and no Shipping Zones defined. Was working previously.
