So I'm no spring chicken to JFBConnect, so you can imagine my surprise when I got this message. Accepting the fact that I am human and can make errors, I went through the setup guide step by step to make sure I had not omitted or incorrectly completed a step. Everything is in order. I am doing a Business Page app. Please get back to me soon as this is taking up far too much of my time on a new project. Thank you.
