Ah, ok. So I did that (deleted the previous page and created a new 'Boards' one) but this is what I see:

I'm sorry but I have no clue, I don't know what you've done wrongly. Maybe the root WordPress .htaccess file conflicts with this WordPress. Slugs may be the same or something else. I'd recommend remove this WP installation with database and files and start again with subDomain. Don't use /community/ slug for WP directory.
