AbleCommerce Shopping Cart Software

We completed upgrading on the weekend, and just tried to place an order via the admin menu for a customer. We get the following error:

Can anyone help?

UPDATE: It seems that maybe the error is only on orders entered from the Admin area, as we were able to place the order from the front end.

I did some tinkering, and found that this is an issue with the country in the billing address. Other orders can be placed through the Admin area, so we narrowed down the issue. As soon as we changed an account to use Canada instead of United States, we get the error. Changing the billing address back to United States clears the problem. Trying United Kingdom also results in the error.

I ran into this also..I hardly ever use the admin order function and I bypassed it by just logging in as the customer...thanks for the work around.

We get people phoning in orders on a daily basis (some of our customers just have to speak to a real person), so this could become a real issue. Fortunately we do not get a lot of international orders, and domestic orders appear to go off without a problem.

I have reported this as a bug, so hopefully it will be handled shortly.
