Layout appears three times!

Hey guys,

I am developing an application for my university and I'm having
problems with the way it's getting rendered. I configured the main
controller to use a layout called "unet-main" and when it displays on
my local machine it works great, but when I upload it to my dedicated
server and try to view it the layout repeat itself three times

My dedicated server runs CentOS 5, I have the latest stable build of
ruby installed, and the latest version of mongrel. All my gems are
updated as well. One detail though is that I use nginx to route the
web requests to three background mongrel servers. (Three,
coincidence?). I also have the latest stable build of nginx.

What do you guys think could be wrong?
Thanks for everything!

No code = no idea.
