Error: The redirect_uri MUST match the registered callback URL for this application

I'm trying to use your plugin but without success. I'm using it as a gh-pages, I tried many Authorization callback URL but without success.

My last try was https://github.com/login/oauth/authorize?client_id= <my_client_id>, the Homepage was configured as http://<user>.github.io/<repo>. I keep getting this error on URI.

PS. I'm not an OAuth expert, so is very possible that I am making some ridiculos error.
