Hi! I followed tutorial from http://www.howtoforge.com/perfect-server-ubuntu-11.10-with-nginx-ispconfig-3, but using Debian Wheezy. It works perfect without any problem. I tried to create an nginx vhost configuration from tutorial http://www.howtoforge.com/running-joomla-1.7-on-nginx-lemp-on-debian-squeeze-ubuntu-11.10, I can access joomla administration but not frontend site and it give me error 503. How do I know right vhost configuration?
