Thanks so iacchus - these instructions are the only ones that worked for me. All others just lead me down a rabbit hole that was never ending.
Only question - I noticed that Apache takes a long long time to complete a restart - is this expected? I also noticed that If I refresh (or close the page) when Apache is hung on restart, it completes the restart immediately. What can be done to ensure it restarts immediately?
