[Plugin: NextScripts: Social Networks Auto-Poster] Error Message: redirect_uri isn't an absolut

When attempting to Authorize to a FB Page the link sent out from the plugin doesn’t properly use the php site code (echo %site_url%) for WP in the redirect_uri. To get it to work properly I removed and replaced with my actual site url in the address bar manually.

Location of error in URL(Cleaned for security)
https://www.facebook.com/dialog/oauth?client_id=##&client_secret=##&redirect_uri= ERROR HERE
