This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing broken links to product categories in French, similar to the issue where links under 'Produits par marque' were not working, this might be due to missing translations.
Solution:
We recommend checking the WPML → Taxonomy Translation for product categories. Ensure that the French plural label and slug fields are filled in. After updating these fields, save your Permalinks to refresh WordPress’s URL structure and clear your cache. This should resolve the issue and the menus should now load correctly in French without producing 404 errors.

Please note that this solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum for further assistance.

Hi, the links to product categories in French are all broken for some reason, can you help? We didn't make any changes and they were working perfectly before. It's the pages in the menu under "Products by brand" In English which are broken in French under "Produits par marque"

Summary:

- The issue was caused by missing translations in WPML → Taxonomy Translation for product categories.
- The French plural label and slug were empty; I filled in all required fields (singular, plural, and slug).
- After updating, I saved Permalinks to refresh WordPress’s URL structure and purged the SG cache.
- The menus now load correctly in French and no longer produce 404 errors.

Thanks
