Background of the issue:
I am trying to make this URL work: lien caché. I have already tried solutions like resetting the permalinks, changing the URL, duplicating the product, and creating a new product with this URL.
Symptoms:
The product page gives a 404 error in all languages.
Questions:
Why does the product page give a 404 error?
What can I do to fix the 404 error for this product URL?
