thanks for the great HowTo - it worked perfectly for me a few weeks ago when I changed the configuration of my ISPConfig from https to http.
However, today I came across a little drawback: I upgraded my ISPConfig to the latest version 2.2.22. After the upgrade, the configuration was running with https again. So I had to go through the same procedure once again.
So, somewhere ISPConfig seems to remember whether it was configured to run via http or https. Do you have any idea where this could be and how I can change it so that the next upgrade runs more smoothly?!
