Bonjour,
je suis sur une mise à jour 1.1.5.2 vers 1.2.0.1, et ma mise a jour est bloquée.
j'ai l'écran en PJ et les logs d'installation me disent ceci :

J'avais un problème de version de php que j'ai mis à jour avant de lancer l'installation, comme demandé)
J'ai donc fait un retour en arrière de la base pour continuer à travailler.
Puis j'ai reploadé une version de la 1.2.0.1 pour refaire la mise à jour.
Et là j'arrive directement sur le même écran.

Une idée ?
