ERROR 500 Uncaught Error: Class 'OrderController' not found in

[gastonaportal2]

Hi, I have a new module for one-page checkout and it's redirected when the people click in the buy button. BUT the problem is when go to the cart and after to show the summary click again to the /order and it error 500. I think that this link need to redirect to the supercheckout module but I don't understand this error:

"Fatal error: Uncaught Error: Class 'OrderController' not found in /home/fh0qf1ph9llh/public_html/mercadofix.com/classes/controller/Controller.php:219 Stack trace: #0 /home/fh0qf1ph9llh/public_html/mercadofix.com/classes/Dispatcher.php(507): ControllerCore::getController('OrderController') #1 /home/fh0qf1ph9llh/public_html/mercadofix.com/index.php(28): DispatcherCore->dispatch() #2 {main} thrown in /home/fh0qf1ph9llh/public_html/mercadofix.com/classes/controller/Controller.php on line 219"

Thanks
