Auto sharing via Ultimate Facebook is not working for me. I receive the following error message: OAuthException: (#100) Invalid parameter.
Hopefully it is un-related to my other issue: https://premium.wpmudev.org/forums/topic/facebook-connect-widget-wont-display#post-352896
Any help would be great!
I have already tried activating, de-activating, uninstalling, re-installing & re-activating the Ultimate Facebook widget—no luck there.
I have also double checked my Facebook App ID and Secret, refreshed user token (just before posting a new post/event).
