I experienced a conflict between Sage and a WPML and WooCommerce combination, where a translated product archive (specificly product_cat taxonomy page) wouldn't be wrapped in the base template. Just the template file contents would be executed without the master/base template. This could be solved by changeing the priority of the template_include filter for the wrapper to >100. I'm not sure if this is WooCommerce specific or if this would be the case for any translated taxonomy when using WPML.
