I have tried the fix above, as I don't need the admin area to be visible to non-admin logged in users, especially as the user_login-out plugin and the favoritesHandler plugin makes the admin area old-fashioned looking and redundant.
When I try the fix above, using the zpBootstrap theme, the tools do indeed disappear for non-admin users, but the space they take at the top of the page remains, throwing off the look of the site. I can't figure out what to do to make the bar at the top disappear as well.
In the theme's inc_header template, zp_apply_filter('theme_head'); is the code that shows that bar (and the tools, typically), but that is needed for the logged-in admin. It seems to be an all-or-nothing fix.
Is there a way to remove the full admin area for non-admins, as suggested in the post above, rather than just removing the tools on the admin bar at the top of the site's pages while leaving that bar? I feel this should be a CSS issue, but I can't figure it out.
Thanks in advance for any help!
Thoughts?
