facebook login not working

Hi, I use facebook Login plugin but it doesn't work
I have set the facebook API and secret key in Plugin as well as Temlate parameter but when clicking the button, nothing happen

Please have a look at our website: http://viethome.co.uk/vietbaby

Your demo template site doesn't work , too

Please help !!

Thanks a lot

At the demo site the button is only for demonstrate template features. Probably the problem is in keys or in domain configuration in facebook - did you set the root of domain ? Please send me via PM the screenshot from facebook configuration page.

Pls find below the app setting

And the APP type is for sure "Login with facebook" ?
