Mise à jour échouée lors d'un ajout de page ou de modification de page sous wordpress

Bonjour,
Lors que je modifie mes pages Wordpress ou que je souhaite les modifier, mes modifications ne sont pas prises en compte. J’ai le message « Mise à jour échouée »

J’ai désintallé tous les pluggins => idem
Réactiver les plugins idem.

Je suis totalement bloquée dans les mises à jour de mon site www.decoration-et-jardins.com

J’ai installé le mode debug et j’ai le msg suivant.

D’avance merci pour votre retour.

Cdt.

Véronique
