Hi John, hi Sylvia,
I finally managed to get it work.
My workaround was changing the redirect_uri manually in the address bar, from https%3A%2F%2Fapps.facebook.com%2F319872171403936%2F to http://www.frankentipps.de/blog/ in our case (if I remember right, I was just trying around and suddenly it worked).
Then I could grant all the required permissions – and it worked.
I hope this helps,
Best regards
Matthias
Thank you for your quick reply. The settings are:
Site URL: https://www.frankentipps.de/blog/
Canvas URL: http://www.frankentipps.de/blog/
Secure Canvas URL: https://www.frankentipps.de/blog/
I changed nothing on the “advanced” tab besides disabling “Deprecate offline access” and “Enhanced Auth Dialog” (as suggested here: http://wordpress.org/support/topic/wpbook-235-facebook-application-settings?replies=1)
Do you see any error here?
