No Shipping Methods Aviailable

I’m using the trial version of Multi-Carrier shipping but I am getting the “There are no shipping methods available” error at checkout. I enabled debugging, but that is showing nothing.

Are there any step-by-step details on how to configure Multi-Carrier shipping plugin with Woo Commerce? I’ve tried every concievable shipping setting in Woo Commerce and the Multi Carrier shipping tab, but I’m sure I’m missing an important config.

Specifically, I’m trying to set up UPS shipping rates based on ZIP code and total item weight. Later I will add rules for USPS shipping for specific products, but for now, UPS is the shipper.

Thank you!
