I'm using OpenFB (https://github.com/ccoenraets/OpenFB) with ionicframework.
When I try to login From localhost It works very fine. When I uploaded my files to another server and I specify the right URL in facebook app, I'm getting this error : Invalid Scope: function
It's telling you the error which no one here will be able to see without the full URL and/or code snippet.
You are supplying a scope labelled function which is not a specified scope in the API.
