Unfortunately the word "Error" isn't very helpful :\

That's because you didn't added FaceBook API correctly.

how to add that API --- correctly

Go to facebook.com and make an application.

I´m getting exactly the same error here.
I´ve already tested this "Application ID" in a wordpress plugin and it´s working.

Created another app, changed ID in plugin options and tested, gives me "Error" => "This page could not be reached" exactly the same from first time.

My forum is using Google SEO, I´ve figured out how to show correct url, but the problem is still there
