Error message showing in footer when using Ultimate Branding.

When viewing the site as a visitor I get the following error:

Warning: in_array() expects parameter 2 to be array, null given in /home/hullcitsupport/public_html/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/custom-admin-bar-files/inc/UB_Admin_Bar.php on line 612

When I am logged in as admin this does not appear.

I tried the usual disable/enable troubleshooting but no luck.

Thanks
Ian.
