Fatal error after updating Ultimate Branding (via wpmudev panel)

Fatal error: Call to a member function get_current_tab() on a non-object in /wp-content/plugins/ultimate-branding/ultimate-branding-files/classes/class.ub.helper.php on line 33
I tried disabling all other addons (as instructed by your colleague before) but when its network activated it keeps giving that error regardless of any other plugins.
