I have the same problem on all of my websites that are updated to 3.8 – just discovered that all the comments are gone, and they are actually not even in the mySQL database, so it’s not just a front-end issue. I can not add new comments – they never show up, even though the comment field is available on the website. Every now and then I get a moderation email that contains no information about the comment:
Author : (IP: , )

These blogs have a variety of themes and plugins – I think the only that they all share is Akismet. I host the websites on a Dreamhost VPS. I have talked to them about the problem, but they can’t help – their backups are not old enough to have the comments.
Very frustrating. Can’t see how an update could delete content from the database, so could this be an Akismet issue?
