itemid 103 is the Survey Page you go to upon logging in using the credentials I provided...so apparently on entering wrong credentials users are getting redirected to that same page. Survey page is not accessible to all users thats why I suppose we come across an empty page.
I remember when I tried this module out with one of the default templates that comes with Joomla, users get a message saying something like "Username and Password are not correct, please check details" - something along these lines, not sure what the exact statement was....Somehow it doesnt display that with my custom template.
Login Redirection Page - SURVEY
Logout Redirection Page - HOME
