Bonjour à tous !

Avant de lancer ma boutique avec Phenix Suite (heureusement, tout fonctionne et c'est une version old school ! :)), je la teste sur différentes versions de PHP. Actuellement, lorsque je passe commande en tant qu'invité sur PHP 8.1+, j'obtiens l'erreur suivante :

@eolia, super boulot ! Je ne connais pas très bien PrestaShop ; j'ai passé des années à développer pour WordPress et vBulletin, donc j'espère rattraper mon retard. Vu la situation, j'étais même sur le point de migrer vers PS 1.6, mais heureusement que je me suis souvenu de ce projet.

Bien cordialement à tous les membres du forum.

PS : Excusez mon français, je suis espagnol.
