Bonjour,

Ma femme a mis en place un site WordPress, et elle a copié-collé dedans un truc qu'elle a trouvé sur un blog.

Et depuis quand elle essaie d'accéder à son compte admin elle est bloquée et fait face à ces messages:

et elle a copié-collé dedans un truc

Peut-être supprimer ce qu'elle a copié

Juste supprimer ce qu'elle a copié dans le code. Si vous n'y connaissez rien ça n'est pas forcément intéressant de faire ce genre de manip, privilégiez un plugin
