 I could not reproduce the "bug", even with all plugins activated, once I
 could get passed it by applying the fix I proposed in comment:1. That
 means : {{{$current_user}}} was set, it was a {{{WP_User}}} object, but it
 had {{{$current_user->ID}}} equal to 0.

 The main issue here is the deadlock. Under an unknown circumstances, the
 admin can login "successfully", but is not identified correctly as an
 administrator, as {{{$current_user->ID}}} remains equal to 0. I'll be
 looking at how {{{$current_user}}} is modified after user or admin login.
