One of my clients recently upgraded his site to WP 3.3 and since that time whenever an administrator is logged into the website, ALL visitors to the site see the Admin bar.
We have tried creating a new administrator account, but the error keeps returning. The real issue is that the admin bar is functional. So if my client is logged in to the website I can simultaneously go to the website on my computer and see the Admin bar and make changes to the website.
Is anyone else having this serious error? Any suggestions on how to fix it?
