We've got a combination phonegap/web app, and am trying to get facebook logins working.
Everything works fine with phonegap, but with the web, Facebook returns the familiar (to many) Given URL is not allowed by the Application configuration...
I've tried using localhost in the Facebook settings, as well as setting up a host on my local machine which used the same URL as our heroku development box (except it has https, which I don't, of course).
I didn't include the port number in the website with facebook login, when using the host as heroku, but tried both with and without on localhost.
Things I've tried
locally - http:localhost:3000 // the app
on facebook
website with facebook login -> http://localhost, http://localhost:3000
app domains -> localhost
locally - http://our-dev-site.herokuapp.com:3000 //the app
on facebook
website with facebook login => http://our-dev-site.herokuapp.com, http://our-dev-site.herokuapp.com:3000
app domains -> our-dev-site.herokuapp.com
I'm really not sure what else to try here. Is there somewhere in the facebook responses that they tell you what URL they are expecting?
-------------- update --------------------
I forgot that our javascript files are actually being served on another port number. The domain for the app is localhost:3000, but the javascript is served from localhost:8080. Not sure if this could be part of the problem.
