Bonjour à tous,

j'ai voulu migrer de la version 1.6 à la 1.7.1 en m'aidant de la documentation 
"mise à jour" de PWG et j'ai bien l'impression d'avoir tout planté !
Si quelqu'un pouvait me venir en aide, je lui serais très reconnaissant.
Sachez que je débute et que pour l'instant j'ai beaucoup de difficulté à suivre.

Voilà ce que j'obtiens :
