I have several authors and comments are being closed on seemingly random posts. Looks like this started around mid-January as a google search of my site for "Sorry, comments are closed on this post" shows earliest instance as Jan 16.
I asked authors to enable the comments, and check the default status of the comments checkbox but they say they are enabling. I enabled on one post that was disabled, but it seems to have switched back to disabled (unchecked). Plugin conflict?
