I'm very sorry you've been experiencing errors when trying to use our Social Share feature to post to Facebook. I looked at some of the most recent posts, and I didn't see any errors on those. Would it be possible to let us know what error you are getting, so that we can help troubleshoot the issue a little further? It may be that you need to reconnect the Facebook account in Constant Contact. Let us know what that error was, and we will go from there!
