[poupy]

Bonjour
Je rencontre un problème lors de la mise à jour de mon site de joomla 3 vers joomla 4.
Joomla ne me propose pas la version 4 pourtant dans les paramètres j'ai bien mis futur joomla
lorsque je passe mon site de php7.4 à php 8.2 j'ai le message d'erreur suivant

Je ne vois absolument d'où vient le problème.
Si quelqu'un pouvait me donner un tuyau
Merci

Bonjour,

Si ton site est en J3, il est fort possible que tu aies des extensions non compatibles PHP 8.2, donc pour passer de J3 à J4, reste en PHP 7.4
Il faudra alors essayer de comprendre pourquoi la maj vers J4 ne t'est pas proposée, d'abord en allant dans la gestion des extensions vider son cache et reconstruire la liste des sites de mise à jour, puis réessayer

C'est parfait dans extension/sites de mise à jour il y avait Joomla! Core qui était désactivé
