I need to translate part of a website. So I had enabled necessary modules : content translation, i18n + i18n sync. Then create some translation of 2 differents content type (after setting them to enable translation).
Put the Language switcher block active, and it appear on translatable contents. But when I want to switch, the link is good but system give me a 404.
In permission level, I see nothing to do .
What is missing in my settings ?
