I can no longer access my Django app via a nginx / fastcgi proxy on Centos 5.7 after upgrading to Django 1.4.2 Upgrading nginx via yum didn't solve the problem. The error message in the logs is: upstream sent unsupported FastCGI protocol version: 60 while reading response header from upstream There's a thread in the Russian list on this error. Can any Russian speakers shed any light onby michela - Nginx Mailing List - English
