No Users Showing Up In Autopost Section

I’ve created the FB app, and this plugin says it’s connected. I’ve already granted extended permissions to the user account.

When I go the “Autopost to Facebook” section of this plugin and try to switch users so that I can use this for my fanpage – there are no users in the dropdown box.

None, nada, nothing at all.

I’ve tried this in IE10 and Chrome. In IE10 I see a dropdown, but it’s completely blank. In Chrome I don’t get anything at all.

There is nothing in the plugin error logs indicating an issue.

I’m using WordPress 3.5.1, and I’ve tried disabling all plugins but Dashboard and Ultimate Facebook. I’ve also tried it in the Twenty Twelve theme. I get the same exact result.

Not sure what to do here.

Thanks,
