I am using the Jigoshop Basic Bundle Shipping extension. However, when I first spotted the problem I disabled all plugins except Jigoshop to check for conflicts and the error still appeared. Also though the below shows Firefox, I checked the cart in other browsers, Chrome, IE, and Safari and have the same problem.
