Pay With A Like working intermittently

Sometimes it works, sometimes it doesn't:

My PWAL plugin seems to work consistently with linked in -but not twitter or facebook.

I was alerted to this via the forums -another wpmu member reached out to tell me the buttons don' t work for twitter:

and I just tested facebook on one of my pages, - I clicked like and the facebook button disappeared, nothing else happened - my like was not posted to facebook, the content was not revealed - the only change was that the facebook button disappeared.
