USPS Shipping Module [Support Thread]

[TooMuchMUsic]

Hello!

One of my customers is attempting to ship an order to New Zealand and is receiving an error. On step one of the checkout it will display the delivery information, but will show "this is currently the only shipping method available to use on this order" but without any shipping method options. When the user clicks on the "continue" button, it will not let then go next to select payment methods. I duplicated the issue by entering a New Zealand address into a logged in customer account.

Upon checking my error logs I receive the following PHP error: "Malformed value for session-based shipping module; customer will need to re-select: false" in my includes order php file. I looked into this issue, and could not find another similar posting.


I am operating on Zencart v1.5.7b and the latest version of the USPS shipping module (2021-05-05 K11a). I am not using zoned shipping and have received orders from outside the UK and Australia recently and from New Zealand in the past. Any help would be appreciated!
