Square for Woocommerce
I left a comment on the themes comment section, I went ahead and purchase support.
I added the square payment gateway to the site. We troubleshooted the page and it seems that the conflict is between the WooCommerce Square and the theme.
If you add something to the checkout and walk through the payment process:
1. if you change the shipping method the system doesn't refresh the page to update the mailing options
2. the square payment gateway form is in active, you can not fill in the labels
If we de-activate the plugin, the theme refresh the page once you change a shipping setting, also if you change the theme
the gateway works.
