Hey there ! I developed a complete website locally with Mamp with english and french locale. Everything was working as expected until I tried it online.

Online all english pages (my default locale) work perfectly, but all french pages give me a "page not found" error. The only french page that is working is the home page.

So basically "website/fr" works, but website/fr/menu doesn't.
