I have issues that might be similar to the things going on here. I have a site using woocommerce and I can't get the UPS part of it working and have no idea why. It says that there is no shipping available in my area (united states).
That seems strange to me...not sure why that is.
So what I did was update WooCommerce and the Theme I am using. The theme default CSS came back which I figured would happen but I have a backup of that. But still the same issue with the checkout process and now the checkout form is all messed up.
Please help me if you know the answer I would greatly appreciate it.
