Replacing localhost part(Getting Error)

[Suprem]

Hello every one I am having a problem with my apache server that I have installed on my os system....

when I replace

Listen **.**.**.78:80
Listen 80

With 

Listen **.**.**.78:80
Listen localhost:80

and I tryed to test it by running the http://localhost/ part after restart and I get a problem loading page??? Does any one know why I am getting this?

This line is invalid:

Listen **.**.**.78:80

I am surprised your server starts, what error do you get?

Problem loading page..That is what I was getting when I put the http://localhost/ in the address bar before changing it everything is fine I get the page that I am suppose too. When I change it that is when I get the problem loading page.

Localhost is only avialable to you. I cannot see what is on your localhost. So what is your error?
