So all of a sudden, after a week of using it, I get an error message on my zabbix server gui (http://localhost/zabbix/.)
zabbix server
The error says: Zabbix serve
Zabbix serve
Edit this file: sudo nano /etc/default/zabbix-server
sudo nano /etc/default/zabbix-server
Adjust the START property to yes:
START
yes
START=yes
Then try to run Zabbix again: sudo service zabbix-server start
sudo service zabbix-server start
