ok, just a trick to that with admin menu editing.
Sorry for that ^^
I’d my all groups entered in that list automatically, and redirected on url base of my site.
All options “on”.
When I tried to add my group for test, a new, not in the list, nothing appear in the both case.
When I’d deleted all redirect rules, all working again… Why ?
If I have, a day or another, to do a redirection on a group, the toolbar will disappear for all others ? Crazy…
