I was trying to change the hostname of my installation, so I followed this tutorial.
Discourse was installed to the default /var/discourse directory.
After using the “./launcher enter app” command I was switched from /var/discourse to /var/www/discourse and followed the next steps.
Now as that still didn’t fix my broken CSS and pictures, I tried to go back to the /var/discourse folder, but it just isn’t there anymore. How can this happen? I cannot find a file called “app.yml” ANYWHERE on the hard drive.
