To change your language settings, log in to elevio and hit ‘Localisation’ in the left hand panel. Here you can select any languages you would like to support.
When a user signs in, elevio will determine their language based on their browser settings and attempt to load content in that language.
If however, you need to force a certain language you can learn how to do so setting the language when loading elevio, like this:
_elev.lang = 'fr'; // for French
