@baris , Ok, you were dead on for some reason my application and secret data is gone from the twitter plugin.
So I went in added the information back to the twitter plugin, restarted the server just in case.
Now I do See the Google+ plugin, of course, and now I see the Twitter however... The Facebook one is no longer there.
I went back into the backend double checked Facebook and all the information is in there.
I then went and disabled the twitter plugin again, and low and behold the Facebook button is back without the twitter plugin enabled.
