Strangest thing happened: all my spam comments disappeared. I have Akismet configured to delete comments more than 30 days old, but it's never deleted all of them. Can anyone think what might cause such behavior.
I'm concerned because Akismet often has false positives & I want to approve such comments rather than lose them.
I'm also using BWP reCAPT to authenticate comments, but I don't believe it would/should delete all of them like this.
