If an Zabbix admin tryies to mass update a "Host" the following error is thrown:

Fatal error: Uncaught Error: Call to undefined function B() in /var/www/html/zabbix.liaison.prod/include/views/configuration.host.massupdate.php:213 Stack trace: #0 /var/www/html/zabbix.liaison.prod/include/classes/mvc/CView.php(139): include() #1 /var/www/html/zabbix.liaison.prod/hosts.php(1086): CView->render() #2 {main} thrown in /var/www/html/zabbix.liaison.prod/include/views/configuration.host.massupdate.php on line 213

Fixed the issue by removing function "B()" from line 213 in configuration.host.massupdate.php
