Blank Page after Login


I have a login page which redirects to dashboard. When a registered user enters his credentials he is shown a blank page and when the page is refreshed it directs to the dashboard. Can any one help me figuring this issue

Check ur action for $this->render string and also right view file exist

can you dump your code here

Thank you all for your replies. I resolved my Issue . Actually I was redirecting twice to a single page and when I removed the second redirection my issue got resolved.
