There was a topic about comments disappearing. Last time it seems to be the issue with FB side and after they fixed that everything has started to work again.
But now the issue is back again (at least for me). But this time comments are not displayed neither for logged in user nor logged out one. Could you let me know about this?
The issue was recognized after plugin and WP update to last versions.
