HybridAuth has stopped working with FaceBook Before the weekend, I successfully set up the HybridAuth module. Upon returning to this project this week (July 1), Facebook logins no longer seem to respond. 

Watchdog logs contained numerous of the following lines

Sand box is off



I'm using the latest library from HybridAuth. I've clone it using git
