Thank you for the help with this. Two problems:
1) When I try to Trash one of my pages, I get "Error moving to trash." All my other forum-related pages have been trashed and the trash has been deleted permanently.
2) I have a Forums>Settings>General tab but there is no "Delete All Caches" button and no Dashboard>Forums >Dashboard tab
See attached image.
Aha! I just noticed a Delete All Caches button on the Forum dashboard, not on one of the tabs. I'm going to assume that is the one I'm supposed to click.
I see all works fine now. You've also deleted wpForo cache. So don't forget about wpForo cache and make sure other cache plugin doesn't cache wpForo. More info here: https://wpforo.com/community/faq/wpforo-and-cache-plugins/#post-37150
I think my forum is working fine (thank you Robert!) except for what I call a "phantom" page https://www.aroundwoodstockvermont.com/community-forums/
There is no reference to this page in WP. I have deleted the trash and cleared all caches (WP and browser) but this URL still resolves!
Hmmm....
