Three main things other than URL, you need to include in your website are
FB API code
and Site name Ex: "Sample"
and Namespace is optional
Earlier I have also generated facebook API, but later it was expired because I have deleted the application in FB
Now, I created new app, and integrated the API codes in my website, and it is working fine.
please check with some online demo hosting provider sites, create your sample site and integrate the API
you can create a sample web site with this hosting site "www.wall.fm"
your url will be "www.yoursite.wall.fm"
my site is www.gsmcommunity.wall.fm
if it works in this site, it should work in your site also..
have a try....
