Is Wpmudev Plugins Compatible with the Divi Theme?

I've installed Divi as my theme and have the Ultimate Branding plugin installed. When I enable the "Custom Admin Bar" I get the following error message.

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

I've enabled other functionality within this plugin without any issues.
