Background of the issue:
I am trying to resolve 404 errors on our site that seem to have started after significant modifications were made in a previous support ticket: https://wpml.org/forums/topic/was-disconnected-during-support-chat/. The issue involves the word 'meubles' being replaced by 'furniture' in product category URLs in our menus. This affects all links in our website's menu, particularly the top-level product category. To see this, visit any product page in French, such as versteckter Link, and hover over the menu options like 'catalogue' and 'Chaises' as shown here: versteckter Link.
Symptoms:
The product category URLs in the menu are incorrect, showing 'furniture' instead of 'meubles', leading to 404 errors. Expected URL: versteckter Link. Actual URL: versteckter Link.
Questions:
How can I fix the incorrect language in the product category URLs?
What steps should I take to resolve the 404 errors caused by this issue?
