Nginx config for enabled sites does not appear to be taking effect any more

I’m trying to get my server setup to handle multiple wordpress sites on nginx.

I followed the different tutorials in the initial server setup, lemp installation etc.

Everything was working ok with the exception of permalinks not working at all. I couldn’t navigate to any page on the front end (away from the domain root).

So since then I have tried a lot of different things messing with nginx.conf and other files (from instructions in the wp codex), but none of that helped, so since then I’ve tried to go back to a clean slate with nginx and php-fpm.

I uninstalled them both, purged, autocleaned, and reinstalled them.

After this, I’ve gone through the basics again and nginx is running, but something is still very wrong. When I go to my server IP, I get the “It works!” index.html from /var/www/ but my configuration should be pointing it to a different document root.

my nginx.conf looks like this: http://pastebin.com/cthXjPyY

my only file in sites-enabled looks like this: http://pastebin.com/mu3Mi9zq

From what I understand, it should be picking up my site’s configuration in sites-enabled rather than loading this file.

I’m stumped, please help.
