Are you logged into your admin panel when viewing the front-end of your site?
The admin bar ONLY appears on the front-end when you are logged into your admin panel.
Yes, I am logged in when I am viewing the front end, but still no bar is showing 🙁
Hmmm… maybe one of your plugins is conflicting… or maybe your theme?
Try to switch to default theme and see if the problem persists. If it does, I’d deactivate all my plugins and test again.
Try to get to “barebones” installation… and see if it works. If it does… begin re-enabling everything until you see it disappear again.
Basically, you’re trying to narrow it down to a plugin… or your theme.
