Any updates on this? I’m having this issue also.
Any updates on this? I’m having the same issue. I upgraded to 2.9, then tried out the option to have comments close after a certain number of days passed. After I removed the option I noticed that none of my posts, even new ones, would allow comments, and that in browsers other than FF a number of comments appeared that didn’t relate to a given post. I tried to restore to a backup and that did not resolve the issue.
ETA: All my comments already say “open” in the database, and other themes are working fine. This appears to be a theme issue.
