Plesk: free port 80 for other app

Question

I have plesk on my web server since it makes setting up emails etc easier. I want to keep port 8443 for the plesk control panel but i want to free up port 80 to use for another service, so how can i get apache/plesk to either stop listening on port 80 or just listen at a different port.

I am using Plesk 10.2 on Ubuntu 10.04.

i searched for quite some time now and none of the already existent tutorials work for me

This appears to be the official instructions on how to do it.

In case you miss it, replace <custom http port> and <custom https port> with the ports you want to use.
