No unread posts?

Earlier today, but after the upgrade, the "Unread Posts" link gave me a list of unread posts.

Now, it gives a message that there are no unread posts since my previous visit, and a link to look at all unread posts.

That link goes to a database error message "Please try again. If you come back to this error screen, report the error to an administrator.".

Is anyone else seeing this problem?

I get the same, without the unread posts feature it will not be practical to use the forum I think, there are just too many posts these days and you have to be able to limit the view to those you haven't read and also only in certain forums.
