Does anyone know how to change the port of SSL?
Right now it's 443, but when I change it in apache to 444 it doesn't work no more. Is there any other config files I have to configure the port in?

I think you missed some of those 443's. Try searching for another '443' in your httpd.conf and replace them with 444.

Nope, there were only two 443 which were changed.

What OS are you using? If you are using the right one, check your /etc/services file for 'https 443/tcp', you'll know what to do from there I assume.
