I'm trying to integrate my project with Facebook. I'm taking babysteps at first and just trying to login, get a Facebook session and get some user data. I'm developing it locally so my Facebook application settings are:
site URL: http://127.0.0.1:8888/mySite/
The canvas URL is the same as above. I haven't specified a site domain.
However, when I click on the login button, I get an error:
API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: redirect_uri is not owned by the application.
What have I done wrong? It's obviously something to do with my Facebook application settings, but I can't see what!
