django-cms not using user's language for its core translations

Question

Edit: found out this happens on a very basic project generated by djangocms-installer, I've reported an issue about this.

I've setup a simple project with django-cms and my client's native language is french. Thanks to Transifex, French translation is always up to date. Not quite sure why, everything related to django-cms app is not being translated (strings in administration, admin toolbar, etc).

Strings like "Double click to edit", "Create Page", etc. are still in english even when Currently logged in user has its settings set to french (Accueil › Cms › User settings › gableroux).

Note that all other strings in administration are translated to french

Administration de Django
Bienvenue, gableroux. Modifier le mot de passe / Déconnexion
Administration du site

etc.

Generated settings

*Note here that I'm not using those settings on production, this is a sample project I generated for this particular issue, SECRET_KEY is not being used anywhere ;)

Answer 1

For the record, this issue has been resolved already on the django-cms project Github: https://github.com/divio/django-cms/issues/3798

The final answer (once the patch was applied that removed the locale fr_FR) was to restart the server -- only with the server being restarted is the locale taken into consideration.
