title: CodeIgniter Controllers functions is not working
body: <p>I have deployed my site on a VPN server. I am able to access the controller constructor, but when I am trying to call any method like <code>mydomain/controller/method</code>, it is not working. However 'mydomain/controller/index' is also not working.</p>
  
  <p>When I am debugging with php method <code>function_exists('my function name')</code> then also it is coming up false even though that method exist in my controller.</p>
  
  <p>Please help with this problem, and let me know if I have to do any config changes.</p>
  
  <p>Thanks!</p>
