This is the technical support forum for WPML - the multilingual WordPress plugin.
This thread is resolved. Here is a description of the problem and solution.
Problem: The printful live shipping rates are only shown when english is selected. In all other languages, the shipping rates are not available and woocommerce switches to the default rates. Solution: You should find the content of class-printful-shipping.php right here: https://gist.github.com/raduconst/4a155ac0c9ebc62318e75a56e9da5e1d. Just simply go to wp-content/plugins/printful-shipping-for-woocommerce/includes folder and replace the content of the file with the one I attached.
