Problem:
If you're experiencing issues with translating menus that contain custom links, which are not being translated or appearing in the String Translations, and you're seeing placeholders like 'Add Exotic Animals @fr' instead of the proper translation during WP Menu Sync.
Solution:
We recommend using the manual translation method for menus with custom links. This approach provides more control and flexibility. You should only add the translated custom URLs when they are available. If the translated URLs are not yet available, wait until you have them before adding them to the menu. This ensures that the custom links are correctly translated and functional.
Please note that this solution might be outdated or not applicable to your case. If the issue persists, we highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If you still need assistance, please don't hesitate to open a new support ticket in the WPML support forum.
