@uidb4056 Sorry to inform you that the free version doesn’t support WPML. but the pro version has.
@uidb4056 Free version support WPML but you can not make an invoice with customer order language. It will generate invoices according to your default language. But we are working on generating invoices according to customer order language. Hope the feature will be available within next week.
@raisa3 You can not discuss pro in the ww.wp.xz.cn forum.
