facebook login "authentication fail"

Hello, I am trying to set up the facebook login, I have read your tutorial but when I try to connect I receive a "authentication fail. acces denied"

Could you help?? My url is http://territoriosnow.com

Thanks

Hi

This mean that most probably a domain You have configured for this app is not correct or it's not activated for public. Either way it's all to be configured in facebook page.

But I should configure it with www. or without www.???

Hi

Depends how Your site is configured in htaccess. Unfortunately I cannot tell that. Best way is to check both options.
