If you are running a multilingual WordPress site where your content (pages, products) exists in multiple languages, use Polylang or WPML.
Polylang (free) – wordpress.org/plugins/polylang
WPML (paid) – wpml.org
These plugins handle switching the entire site language based on the visitor’s preference or URL. WP 3D Configurator works alongside these plugins.
NOTE: Configuring multilingual setups is beyond the scope of this documentation. Refer to the Polylang or WPML documentation for setup instructions.
