CakePHP Questions

I have a controller which checks a date range and if there is a problem it displays a message. I have installed the application on a new server and suddenly the flash-message isn't displaying when the user selects an invalid date range. I am using the same hosting company so essentially all that has changed is the app url.

The code to display the message is as follows:

// redirect if any errors in date range
        if(count($msg[0])>0){
            $flashmsg = implode('<br />',$msg[0]).implode('<br />',$msg[1]);
            $this->Session->setFlash(__($flashmsg, true),'default', array('class' => 'flash-message-success'));
            $this->redirect(array('action' => 'feedback'));
        }

The feedback() function is simply setting the layout to use.

Any advice would be greatly appreciated...
