I'm building a site for an organisation which requires individuals to be able to log in. As Administrator, I see the black Admin bar at the top. I've just logged in as Author, and the top bar is missing.
Previously, all roles were able to see it, and I am relying on it for folk to have access to editing their Profile and Public Profile, and also to log out. Some people have also been authors, as a simple way of managing events.
Why has it gone? And how do I get it back? I have recently upgraded to WP 3.8 and notice a lot has changed in the presentation of the UI - is that perhaps a factor?
