Tried a bit of the troubleshooting you did @clou4394. I installed it on another website using that website’s facebook app and the widget also showed nothing there. I then tried ‘Get Access Token’ on both sites and was able to get the corresponding tokens for each app. When I put these in, on one site (the 1st to get the token)showed the same thing, blank widget. The 2nd site though showed your “Caught exception:..” error and when I removed the 2 access tokens from both sites all went back to normal (blank).
All this may be completely irrelevant, but it’s satisfying to know that I’m at least getting some response (error message).
Really need some help here @roidayan. I’m stumped! ??
