No, that's what I meant, I missed it on first reading I was rushing. (as I am now, I fear, so if I miss something you already wrote that you did, I apologize.)
There should be a file in /usr/local/etc/ezjail called
www.doman. As for ezjail.conf.sample, you should be able to leave it alone, rather than renaming and uncommenting it, unless things have drastically changed.
Maybe that's the issue?
Did you look at the page I mentioned? If not, go back and try it that way again and see if you have any luck.
