From the Maglr dashboard, go to the Settings tab, this area allows the user the change many different settings to do with the Maglr dashboard, editors, and publications.
Once in the settings tab, Click the Multilingualism icon under General. This will direct you to a new page with a list of different languages and tick boxes next to each one.
With the list of languages, you need to click to tick the boxes you wish to have available for when you publish/make a publication, for example If I make a publication that is in English, I would need to enable the English language here.
Now when you make a new publication, the settings have been set so that the publication will be under those languages the user has selected.
