title: Codeigniter functions return "404 Not Found" except index()
body: <p>I have a controller with two functions : <code>index()</code> that echoes <code>Hello World</code> and <code>getTs()</code> that echoes <code>Hello again</code>.</p>
  
  <p>When I call <code>163.XX.XXX.XX/API</code>, <code>index()</code> returns what it's supposed to.
  However, when I call <code>163.XX.XXX.XX/API/index.php/ApiController/getTs</code>, I get a <code>404 Not found</code> error.</p>
  
  <p>I've tried calling the URL in different ways, without <code>index.php</code> for example, but it doesnt change anything.</p>
  
  <p>Class names are written with the same case and URI Protocol is set to <code>REQUEST_URI</code>.</p>
  
  <p>The server is running Nginx 1.10.3.</p>
  
  <p>Thanks for your help.</p>
