Turning Off the WordPress Admin Bar
As you progress in developing your website at EWU you might find that the black admin toolbar is a distraction or is blocking you from previewing your content. Most people find the WordPress admin toolbar useful, but some people may want to turn the WordPress Admin Bar off from the front end of the site. Remember, the WordPress Admin Bar is only visible to you when you’re logged in to your site.
To turn off this view, in the top right of the Dashboard, under your Profile (Howdy, "your name" text), click the Edit my Profile (Screenshot #1) link. From this screen, you’ll see a check box to Show Toolbar (Screenshot #2) when viewing site. Simply uncheck this box to turn this view off, then scroll to the bottom and click Update profile.

If you return to the front end of our site, the WordPress Admin Bar will be no longer visible. If you decide later that you’d like to turn the Admin Bar back on, just return to your edit profile and check the box to show the toolbar again.
