[Grok-dev] skin object not find ++skin++plus

[DIVINE, PAUL (PAUL)]

Hello grokkers,
I am using the great book "Grok 1.0" of Carlos de la Guardia,
at the chapter 11 "Key Concepts Behind Grok". The purpose is to add a skin chooser with second package called todo_plus.

After http://xxxx/++skin++plus/todo/index

NotFound: Object: <zope.site.folder.Folder object at 0x279bb90>, name: u'++skin++plus'

It seems that the second package is not in action.
Thanks in advance for your help.

Paul
