The most common cause with channel owners in the backend:
In the JFBConnect backend, if the list of users to select for a channel owner is empty, this means that no users have authenticated with the social network set up in the channel. For instance, if you're doing a LinkedIn company channel, you will need to have authenticated and logged in on the front-end with LinkedIn credentials for the user to show up in the list. To remedy this, login on the front-end with the login button for the desired social network provider. Please make sure NOT to log in with Joomla credentials. Once the user has been created and logged in, refresh the channel in the backend. This will re-populate the list of available users to select.
If this doesn't help resolve the issue, please describe what you're seeing in more detail.
