Hello!
I don't understand why when I insert the url of my page into the FB widget, it says " Invalid Facebook Page URL" ?
Why is that???
Maybe someone faced such a problem, I will be very grateful for the help)

Answer 1

As far as I remember, you need to insert not the full url, but only your identifier.

Alas, I can't check it myself.
