This is probably the same bug. My issue is that after turning on auto-close, only posts created after setting the auto-close time will be auto-closed. Even if someone drags up an ancient post with a new reply, it doesn’t have the auto-close notice at the bottom of the page. I was hoping that there would be a nightly job or something to look for topics past the auto-close time that are still open, and then close them.
Is anyone aware of a workaround for my issue? Is there some command I can run to close topics that are older than the configured auto-close time? I’m not to keen on closing a year of posts manually.
