I've just deployed a new env and I'm getting some strange thing.
In the frontend, my static files load properly from my custom theme
frontend/Website/default/fr_FR
But once I come into the admin, all my assets are broken. This is due to the fact that my backend is trying to load from
adminhtml/Magento/backend/en_US
instead of
adminhtml/Magento/backend/fr_FR
My question is : How can I make sure the backend load with the correct settings ?
