Facebook API v2.11 is throwing a 400 Bad Request

[JRetza]

Description

When using this plugin with a newly created Facebook App (API v2.11) an error is thrown on post.

Steps to reproduce

1. Create a new Facebook App as normal using the latest API 2.11
2. Configure your OAuth & Social Poster plugins, attempt to use for Facebook
3. 400 Bad Request Error

Additional info

• Plugin version: OAuth 2.1.1 & Social Poster 1.2.2
• Craft version: 2.6.2994

The only way we could get this to work was to spin up an old testing app in Facebook that was using API v2.5 - we updated the API to v2.8 and everything functions as normal. Unfortunately, you cannot 'downgrade' the version of the FB API you come in on - so if you make a new FB App today - you can only use API v2.11 (which throws the error described above).

Should be improved in 2.0.0, but please there are potential issues with Facebook
