Shipping Error

Hi there,

We have installed a plugin for shipping calculation, and the plugin works fine in other site with storefront theme.

We are having an issue calculating shipping with this plugin in woodmart.

The console said this:

Failed to load resource: the server responded with a status of 500 ()

And then when we refresh the browser we have this:
