Shipping estimator fails even with fedex disabled and customer not logged in. If there is anything I can do to help, please let me know.
This one v1.7.6 might not be in the zc plugins section but I think it is the latest and only available option for Fedex.
If you know of any different variant for Fedex, I'm all ears.
