    Just loaded new version of WP on the following site:

    Uploaded the custom theme and the *sql file and now I'm getting the following message appearing at the bottom of each page in the site:

    Fatal error: Call to undefined method Custom_Admin_Bar::add_group() in /home/content/36/7730036/html/wp-includes/admin-bar.php on line 169

    Any help appreciated,
    Thank you,

    Are you still having issues? I didn't see the error message when I went to the site.

    I am still getting it.
    Try navigating to one of the other pages. It seems to appear right after that for sure.

    And I appear to have also lost all the posts and some of the elements within the dashboard are acting weird, e.g. the drag and drop widgets page is not working.

    I'm thinking I should just revert back to 3.3

    Still not seeing anything but looking at the error message you posted, it as to do with the admin header that's added when you are logged in, so only logged in users will see that error. You can try verifying this by going to your user page and disabling the toolbar and seeing if that gets rid of the error message for you.

    Typically something like this, plust the other issues you're having, are due to a incompatible plugin or theme. This can be verified by disabling your plugins and switching to the default theme to see if the problems persist.

    I think this error is only visible when you are logged in as it relates to the admin bar. Try:
    - switching to the Twenty Eleven theme by renaming your current theme's folder in wp-content/themes and adding "-old" to the end of the folder name using FTP or whatever file management application your host provides.

    - resetting the plugins folder by FTP or phpMyAdmin.

    - re-uploading all files & folders - except the wp-content folder - from a fresh download of WordPress.

    - re-running the upgrade via wp-admin/upgrade.php
