Hi

I was checking out the application Contact Viewer.

I took the code from https://github.com/ForceDotComLabs/Contact-Viewer

And also performed all the steps mentioned there.

Now once i go back and hit the URL of my site, then instead of the application I get the following error:

error=redirect_uri_mismatch&error_description=redirect_uri%20must%20match%20configuration

I check out few things. The redirecturi is coming null in the URL and hence this error is coming. 

redirectUri is equivalent to the callback URL provided in the Remote access detail and i have provided the same (Call back URL = my force.com site's address).

Can anyone guide me as to how to solve this error?
