Energized,
I don't know the plugin you're using. If you're using JFBConnect, please let us know the page it's on, and post from the account you subscribed from. Otherwise, we won't be able to help you.
Aleksandar,
Can you try adding one (or both) of the following lines to the Open Graph configuration area in JFBConnect:
app_id=<YOUR APPLICATION ID>
admins=<YOUR FACEBOOK USER ID>
This may help let Facebook recognize you as an administrator. It should work automatically, but we've seen it needed to be forced in some cases. Please note, that you need to have the Open Graph features enabled in JFBConnect.
Hope this helps, and good luck!
