WCML

Problem:
The client is experiencing an issue where the translated WooCommerce product base slugs are not correctly applied to single product URLs in a multilingual WooCommerce + WPML staging site. Despite correct settings in WPML and WooCommerce Multilingual, the German single product URLs still use the Dutch product base instead of the translated German base.
Solution:
We recommended the client to ensure that the option 'Set different slugs in different languages for Products' is enabled in WPML > Settings > Post Types Translation. After enabling this setting, it's crucial to save the base slugs for different languages and then save the changes. Additionally, the client should navigate to WP Dashboard > Settings > Permalinks and save the settings there to clear the permalinks cache. This action should resolve the issue with incorrect URL slugs.
