Same issue, thumbs not showing. Gallery pop up works fine when clicking on blank thumb nails,

The gallery thumbnails are not appearing because the Facebook CDN no longer permits hotlinking (i.e. accessing and using images and other assets directly on pages on domains for which the content is not intended). The plugin will need to be updated to pull down all those images and upload them to your personal sites before it will ever be useful again. Your best option now would be to download the images yourselves, upload them to your sites, and create galleries manually or with another plugin.
