Argument Error after update

Since the second last update, I have been unable to get rid of the Wordpress menu in the admin bar (on all sites including different themes) and since the Version upgrade, the W is still there and am getting this error now too:

Warning: array_intersect(): Argument #1 is not an array in /home/xxxxx/public_html/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/custom-admin-bar-files/inc/UB_Admin_Bar.php on line 621

everything still seems to be functioning, just can't turn off the wordpress menu (running 4.2) and that error line is displaying
