I'm having some trouble with the Ultimate Facebook plugin. When logged in as network administrator, I'm able to use the facebook photo dialog on the post edit screen. However, when I log in to any network subsite and authenticate with my facebook account, I can see the icon for "add FB photo" and click it to open the dialog, but the dialog is just blank. Nothing loads in the window.
I've tried authenticating with a couple of different facebook accounts, but no luck. Any ideas?
