i have error when i click facebook connect button.
i created you extension subdomain. e.g: (app.example.com)
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.
when i added (example.com) worked but subdomain (app.example.com) didn't work.
Meanwhile i set up application iframe.
Why ?
