after upgrade to v2.4.4 getting UNKNOWN in trigger but event exists,
once I downgrade web to v2.4.2, it fix the problem
(yum downgrade zabbix-web-mysql-2.4.2-1.el6.noarch zabbix-web-2.4.2-1.el6.noarch)
in my env. Zabbix server,DB,web installed on separate servers (centos 6)
Can I ,as workaround, downgrade only web to v2.4.2 and stay with server & DB v2.4.4 ?
