Hi,
For some reason, when I go to my cart, my standard tax rate of 10% internationally shows, however when I go to the checkout the tax rate shows “$0.00” but when you get to the thank you page and get the email confirmation it shows the tax rate of 10% and woocommerce captures the payment including the tax rate.
I’ve been using this theme for 5 months with no problem, not sure what happened.
Please make the full backup of your site as well as the Theme settings export and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by Woocommerce.
