Solution – Mac OS 10.14 Mojave – 48)Address already in use: AH00072: make_sock: could not bind to address [::]:80

Apache stopped working for me all of a sudden when I upgraded my Mac to Mojave. I attempted to shut down all of my Apache processes running but still had no luck. What I found was I had to disable OSX’s built-in Apache Servers: After doing that, I restarted and everything was working again!
