Hi Alex,
Thanks for the reply. I've checked the backend and here are the findings:
1) Opengraph plugin - Disabled (Both jReviews & JFBConnect) - Please see attachment
2) jReviews Config - OpenGraph is enabled
3) JFBConnect OpenGraph - No Objects & Actions are created.
The problem happens only when there is auto posting either via Facebook itself or via Twitter to Facebook or via IFTTT to Facebook.
