Hello Chouby!
Thank you very much! It seems I had not searched well.
I have found it exactly where your page indicates.
I have a second related question, to complete the topic.
This option “Hides languages with no translation” works perfectly, but there is ONE exception: the HOME page.
When I have added a few weeks ago for some tests, a 6th language (Serbian), the Serbian flag was constantly showing but only on the HOME pages.
Do you know if this can be avoided ?
Vincent.
