Hi!
I am sorry you are having trouble with this. I will do what I can to help, although I am not sure what could be causing this.
First, is your Xapo app "Redirect URI" set to your site's URL? It looks like it is, but I thought it might be worth double checking. And it might be worth checking to make sure none of your keys have any extra spaces or anything, although I doubt that is it, too.
Did you make any changes to any of the .php files?
I am trying to change my own script / app to see if I can duplicate the message your site gives. I hope that we can get this fixed for you!
