Yeah. I had a port 80 problem when Dropbox was running in the background. As soon as I changed that (i.e. now Dropbox only runs when I open it instead of when I switch the laptop on), my problem was fixed. You can see what occupies your port 80 by running sudo lsof -i :YourPortNumber.

Yes, I've tried the DropBox trick but still macOS won't let my process use port 80 unless I start that process as root.
Not sure how that link you offered helps?
Eh how annoying. Well you could add root permissions to other users and then you should be able to close the port.
Ah, is that what that link was about?
Exactly :)
Okay, I’ll take a closer look and let you know how I get on.
Thanks for your help.
@sylwia - That link seemed to be about file permissions rather than process permissions.
See my reply to Mateusz where I use the insight provided and find my solution,
