Where is the setting 'Can Access Admin CP' to be found in IPB4? We have a couple of user groups who aren't administrators but who have access to AdminCP for maintenance tasks.

If I make a copy of the Administrators group and move users into it, they lose AdminCP permissions etc.

In 3.4 there was a tickbox but I can't find it now...

ACP -> Members -> Staff -> Adninistrator

Add the group there and add restrictions, if you want.
