Problem:
The client was experiencing 404 errors when trying to access translated versions of their pages. The issue was related to the disappearance of translation links in the menu, which seemed to occur intermittently, often after automatic updates. The client had integrated absolute links of the pages into the menus rather than selecting these pages directly in the menu settings.
Solution:
We recommended that the client delete and recreate all menus in the required languages (FR, EN, DE) and then use the WPML > Synchronize WP menus function to ensure proper synchronization. It's important to note that custom menu items can only be translated using WPML > String Translation or adjusted manually within each menu, as WPML Menus Sync cannot automatically handle custom menu items. For more detailed guidance on translating menus, please visit Translating Menus Documentation.
