MVC script architecture

I am writing a social network with MVC architecture, it works localhost (wampserver) correctly, but when I upload it to a real host, I get this error at http://example.com/

Warning: require_once(views/index/index.php): failed to open stream: No such file or directory in /home3/farazenc/public_html/fb/views/index.php on line 14

Fatal error: require_once(): Failed opening required 'views/index/index.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home3/farazenc/public_html/fb/views/index.php on line 14

      

        
        
        
      

    

and my method doesn't work, for example when I go http://example.com/index/register should show registration form but show 404

my main file: .htaccess
