Marc, thank you. Issue has resolved itself, unless you clicked a button. The issue was brought to my attention yesterday by a manager, and until this morning (8 hours ago), it didn't seem to work. But now it does. I don't really have an explanation -all the settings I changed, I then reset. But the browser, MS Edge, I see took 5 min to update a new post to the recent posts section today, despite refresh clicks and shift+F5. Open Club reply posts now appear in recent posts on the front page.
Thanks again.
