I'v uploaded a CodeIgniter application from my localhost with Apache to a server running Nginx.
Its works perfectly on my localhost and on other server with Apache.
It's under a subdomain, an domain and other subdomains are running PHP 100%.
This application in CI doesn't start, and PHP is returned without being compiled.
This is what I get on /var/log/nginx/error.log:
2013/12/05 14:50:31 [error] 20139#0: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error: Class 'M_website' not found in /home/webroot/domain.com/cms/system/core/Loader.php on line 303" while reading upstream, client: 84.91.4.220, server: cms.domain.com, request: "GET /websites HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "cms.domain.com" Class 'M_website' not found in /home/webroot/domain.com/cms/system/core/Loader.php
This is my subdomain conf.
