Hello,
We can’t get access to your WP Dashboard after logging in https://gyazo.com/9757288651d55d4b09020aa0cb26d8f5
Besides the mentioned error is a known error and is related to the Elementor plugin https://wordpress.org/support/topic/uncaught-error-call-to-undefined-function-wc_get_chosen_shipping_method_ids/ not to our theme. So, contact Elementor plugin support to fix this https://wordpress.org/support/plugin/elementor/
Till the issue is fixed deactivate the tax calculus on Woocommerce > General.
