So today, I spent hours trying to recover my server. I installed some files on what I thought was the testing server and found out it was the primary server. It all started when I decided to install this Graphical User Interface (GUI) and to run some other commands. After I got through all of the installation steps, I ran one command that made my server go down for eternity. It was systemctl isolate graphical. After I ran that command, the screen went blank. Then, a total system failure occurred. I couldn’t access my website nor server control panel, it seemed like the server was inoperational. I eventually had to scrap the server and start all over from a VERY outdated backup. For now, my server is 60% recovered with the KhoiUSAhoster and social feeds missing. It costed me a lot of time and data so I hope you don’t make the same mistake. (Unless you aren’t as technical as me)
