Quelle erreur obtiens tu lorsque tu exécutes une commande d’authme ?

Cordialement

pas uniquement authme, n’importe quel commande ne marche pas. ça ne m’écrit rien
j’écrit la commande mais ça fait rien

et je viens de découvrir qu’en fait, c’est un problème d’essentials car depuis que je viens de le désinstaler, les commande basique marchent!

mais comment le régler svp?

c’est bon j’ai trouver le problème, j’ai dû repasser en 1.7.10 car en 1.8 ça ne fonctionne pas!
