me too i can’t work this out at all..
it works on all my other websites
follow and try my way to reduce plugin conflict.
deactivate all plugins related to FB except NXS.
(from my exp, i cleaned up the dbase from any fb app related).
unregister your FB app from your FB ID (go to setting > app > remove app.
reset all cookies from browser or the site cache
logout from wp and then login again (optional but recommended)
setup the NXS again from the beginning (fb app and key and authorize)
it’s works for me.
I have this problem with jetpack activation, but I dont have any facebook plugin 🙁
