I've tried to find this one, but maybe I'm the only one with the problem?
In the last few months, I've noticed that my blog seems to randomly close comments, as if I had set the "automatically close comments after X days", which I don't. When I look in the DB, the comment_status has all entries updated to "closed". I have no idea what's setting these. I have to do an update statement to change them all back to "open".
I thought this might be a plugin, but I couldn't figure out which one it might be.
Anyone else seen this?
