This is a multi site installation. Sites added prior to activation of Ultimate Branding didn't show error codes.
I created a new site after installing Ultimate Branding and I got this message:
Warning: in_array() expects parameter 2 to be array, null given in **** core/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/custom-admin-bar-files/inc/UB_Admin_Bar.php on line 612
This message continues to appear in the dashboard of the site added AFTER activating the Ultimate Branding plugin. (see screen shot)
It does not appear in sites created before Ultimate Branding was activated.
