Um, actually, it does.Indeed this is as designed. You can manually make anyone you want show up as staff, but by default, making someone an administrator doesn't give them any permissions to take action in the forum itself, so to an end-user, they're not likely to be the kind of person that should be contacted about issues. (Think technical administrators, for example.)
Well, duh, yes, I know the default user is the super administratorAn administrator that isn't a moderator doesn't have any permissions to perform moderator actions.
The default user created during install is a moderator, administrator and a super administrator.
I did look up. Essentially, by default, XenForo has no administrator (except for the super administrator).As I already said, I would suggest reading up how things work.
Adding someone to the Administrative user group does not make them an administrator.
