Hi, Dalvio.
Error notice explains it all:
"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."
You provided wrong URL in app configuration. Probably you provided without www and your site is available with www only. If you have doubts how to configure your app - please contact with Facebook support as this is Facebook issue ans requires Facebook support.
Hi, Dalvio.
Responded via PM.
Hi, Dalvio.
Now error is different:
"App Not Setup: The developers of this app have not set up this app properly for Facebook Login."
Script insertion is fine as hundreds of users successfully are using this feature.
I need to see every page of your app setting to advise you something useful...
The error was different because I've tried by myself to put the script recommended by FB just after <body> of my template index.php. It was just a try, but I've turned back right before.
I just don't understand. I've just set app as recommended and inserted data on JS settings.
Have you seen the scripts screen caps I've sent you by PM?
HI, Dalvio.
Yes, I saw them. But there is much more to set. Also apps need to be send to review to Facebook.
That's why I advised you to contact with Facebook support.
