Thanks for the quick response.
I just tried but unfortunately it doesn’t work:
Commande : SITE CHMOD 744 utils\gallery.sqlite
Réponse : 553 Prohibited file name: utils\gallery.sqlite
A misconception in my app caused the creation of this file but I have solved that point.
I think the problem lies in the server configuration and I can’t do much from here. Hoping an infinity mod pass by to help.
