title: Why does Codeigniter 2 routing work but not on Codeigniter 3?
body: <p>I am developing a project on codeigniter 3, but I have a routing problem. </p>
  
  <pre><code>$route['forgot-password'] = "Auth/forgot_password";
  </code></pre>
  
  <p>when I request the url it shows an error, the error is given below</p>
  
  <pre><code>http://localhost/myproject/forgot-password/404
  </code></pre>
  
  <p>It works fine on Codeigniter 2 but not working on Codeigniter 3.</p>
  
  <p>Thanks in advance</p>
