Zabbix server is not running: the information displayed may not be current

Question

So all of a sudden, after a week of using it, I get an error message on my zabbix server gui (http://localhost/zabbix/.)

The error says: Zabbix serve

I solved this problem on Ubuntu 18.04 by uninstalling Zabbix and reinstalling it again from scratch.

The initial installation didn't work because I had followed old posts/guides/tutorials, even from Zabbix documentation itself, so these might probably be outdated. So, the trick was to find and follow the most updated guide to Zabbix installation from its docs.

Here are the two links I followed for uninstalling and reinstalling Zabbix:

• How to uninstall Zabbix: https://www.quora.com/How-do-I-uninstall-Zabbix-server-agent-in-Ubuntu
• How to (properly) install Zabbix: https://www.zabbix.com/download?zabbix=4.0&os_distribution=ubuntu&os_version=18.04_bionic&db=postgresql

When installing Zabbix from the link above, your choosen Zabbix Version, OS Distribution, OS Version or Database may be different from the ones I've selected, but following the instructions on this page will probably be also the right way for you to install your chosen Zabbix configuration without getting errors post installation.
