you don't have to change there
at this place you can translate english phrases into french (if the translation is missing)
wpForo uses the language setting of Wordpress
more information you can find here > https://wpforo.com/docs/root/translation/
Both screenshots show French language
So you only have to translate the missing phrases
Did you read this > https://wpforo.com/docs/root/translation/
Do you use Loco Translate or how did you translate everything?
Humm The first screenshot ( Screenshot_30.jpg) of the first post have just "English" in the dropdown menu.
In my second post i screen (Screenshot_29.jpg) the general setting with my site in French.
Am i missing something ?
I would prefer to use loco translate but i read that i can use custom localization to save the file.
So i don't want them to be erased when i'll update Wpforo.
I think it's safer to use the "Phrase" module isn't it ?
