Connexion WP admin et page blanche… (Créer un compte)

Bonjour,

Ma configuration WP actuelle :
– Version de WordPress : 2.5
– Version de PHP/MySQL : 3 (pas sûre…)
– Thème utilisé : greenling
– Extensions en place : twitter, page order, akismet ?
– Nom de l’hebergeur : IXWebhosting
– Adresse du site : http://www.diegohartfield.net

Problème(s) rencontré(s) :
Login : nom d’utilisateur + password + ok = connexion impossible : une page blanche s’affiche sans aucun message d’erreur.
Je sors de la chatroom de l’hébergeur et le php + mysql fonctionnent à merveille. Le problème vient de ma base de données. Mais où ? quoi ? quand ? comment ? pourquoi ?

Au secours.

Voilà ce qui s’affiche dans mon wp-login.php via le serveur ftp :

J’ai désactivé l’ajout de commentaires il y a quelques semaines et modifié mon mot de passe, mais j’ai utilisé WP plus d’une fois après ça et tout fonctionnait parfaitement.
