If anyone is still having an issue with this plugin sending notifications, here’s a fix:
Edit these files in the wp-content/plugins/facebook-comments-for-wordpress/ directory:
facebook-comments-ajax.php
remove lines 2-4:
if (FBCOMMENTS_ERRORS) {
error_reporting(E_ALL); // Ensure all errors and warnings are verbose
}
facebook-comments-display.php
change line 162 to:
FB.Event.subscribe('comment.create', addedComment);
In the advanced settings for the plugin ensure this is checked:
√ Include Facebook JavaScript SDK (This should be checked unless you’ve manually included the SDK elsewhere)
