Hey @heathg,
Try to enable and disable plugin may be it work, although version 2.8.3 working fine in my site.
Hey @gbatkhuyag Check the App’s Facebook Developer Account, there will be more information related to this query as this URL is blocked by Facebook so I guess there must be valid Reason to do this Check your Facebook Developer Account.
@renatonogueira No, not yet but I use another plugin (Called Super Socializer) which worked for me but any case it didn’t work too then talk with hosting Support like in my case it didn’t work with Primary Hosting too.
Update make it fix, no worry 🙂
