As of May 2015, Facebook is retiring its API 1.x, which this plugin relied on in order to pull album/photo information from Facebook without needing an access token to do so. With API v2.x, an access token is now required for ALL Facebook profiles, including profiles for businesses or organizations, that did not require tokens before.
As a result, this plugin now also requires a Facebook APP and the subsequent access token in order to retrieve any data from Facebook.
The plugin includes a dedicated page in its settings that can be used to automatically generate an access token and convert that token into an extended token, after you created a Facebook APP via Facebook itself. Each gallery also includes a dedicated setting option, allowing you to assign an access token to the gallery.
If you have problems with creating a Facebook APP and token, the tutorials on the following pages have proven to be helpful for others:
