Is the redirecting really working? It doesn't seem so to me. After all, htaccess doesn't work with IIS. Other than that, unfortunately, I don't know much about it.
My little htaccess rewrite knowledge has long been forgotten, or I would commend on your rewrite code as you wrote it. But it doesn't seem right, if you ask me.

http://empleos.8va.cl/css/reset.css doesn't exist, and the same probably goes for the rest of the CSS files. Are you sure you have uploaded all the needed files to that account/folder?
