**Menu de la crèche**
Menu {{ menu_type.upper() }}:
Malheureusement, une erreur a eu lieu lors de la récupération des menus.
Etant donné la complexité de la récupération des menus, on peut envisager que cela est dû à un jour férié.
D'autres hypothèses peuvent toutefois être envisagées
Veuillez contacter le développeur pour plus d'informations...
Il est bien mon texte ? Il fait très pro, je trouve :D
