The plugin has been working completely fine since I first set it up. Now having made no changes I am suddenly getting this error on certain posts:
Fatal error: Uncaught Exception: 1: An unknown error occurred thrown in /wp-content/plugins/seo-facebook-comments/facebook/base_facebook.php on line 1273
This doesn't happen on all posts and sometimes activating and deactivating fixes it temporarily but it always recurs.
I've tried browsing around and it seems like a few people have had the same problem but there hasn't ever been any solution.
Any help is much appreciated as otherwise I'll have to stop using the plugin.
