social plugin re-redirects to wrong adress

Hi guys.

I have just installed the social media log-in plugin on my site

http://www.amsn.com.au

i wish to have it the login appear here

http://www.amns.com.au/pop-quiz ( page is hidden from top menu at moment )

when i log out and log in using facebook i get redirected to this page

http://www.amsn.com.au/online-learning-modules/

i have no idea why.

i have changing the settings repeatly in the re-direct options but nothing seems to help.

any suggestions ?
