Sinon, tu peux cacher ces vilains messages d'erreur en ouvrant le 1er onglet du plugin Local Files Editor, en y collant cela :
$conf['show_php_errors'] = E_STRICT; 
+ enregistrer

C'est cacher la poussière sous le tapis, mais ça permet d'y voir plus clair le temps de trouver la solution.

N'oublie pas que je ne suis pas codeur. En dernier recours : le forum de Piwigo : https://fr.piwigo.org/forum/

J'espère que tu vas bien!

Je viens d'installer Piwigo version 15.7.0 et je vois beaucoup d'erreur.

As-tu eu ce genre de problèmes et que faut-il faire pour régler ces problèmes?

Voici les erreurs rencontrés:
