unable to log in- connect with facebook

[navnit]

Hello,
I am using joomla 3.0.x for my website.
I installed phoca gallery it is working well. It also connect with picasa successfully.
when i am log in- connect with Facebook after entering app id & app secret (also created app id in Facebook) it shows error like "Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains."

Can anyone help me.
Thank & Regards
Navnit

go to https://developers.facebook.com/apps/<AppId>/summary

Under section: Website with Facebook Login
fill the field Site Url e.g. http ://www .example.com or http :// localhost (interesting, also supports localhost)
