Is the Facebook page really a page?
This works for pages if you follow the shortcodes. To test it out, go to https://graph.facebook.com/___gallery_id____/photos/ if this displaying something that looks like an error, then it’s actually a facebook profile. (The id, is the first set of numbers in the url bar, when you’re viewing the gallery on facebook).
The icon should be beside the upload images icons on the edit post pages, above the editor window.
If you could post the response you get from the above test, that would be awesome.
I have seen this on one user’s site, where the plugin just didn’t work. I’m not sure why, maybe cURL isn’t running, or maybe the permissions aren’t set right.
The start of a proper graph response:
