title: CodeIgniter and Nginx - Class not found
body: <p>I'v uploaded a CodeIgniter application from my localhost with <strong>Apache</strong> to a server running <strong>Nginx</strong>.</p>
  
  <p>Its works perfectly on my localhost and on other server with Apache.</p>
  
  <p>It's under a subdomain, an domain and other subdomains are running PHP 100%.</p>
  
  <p>This application in CI doesn't start, and PHP is returned without being <em>compiled</em>.</p>
  
  <p>This is what I get on /var/log/nginx/error.log:</p>
  
  <pre><code>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"
