[Resuelto] With www redirect from subdomain to main domain

With a wordpress/woocommerce/wpml site we have an issue with www. and without www. The site is installed on enlace oculto with a DE language on enlace oculto . And it works perfectly. But when a customer goes to enlace oculto it is redirected to super-seat.com and not super-stuhl.de. How can I fix this?
