How to remove /community/ from the URLs (not change it, but remove it)?
E.g. instead of https://wpforo.com/community/how-to-and-troubleshooting-2/ I would like only https://wpforo.com/how-to-and-troubleshooting-2/
I'm pretty sure you can't do that. Because You must have a page for the "base" of the shortcode of wpForo.
But probably you can make it short and unoticable, like a single letter?
You can do that if you enable the "Turn WordPress to wpForo" option in Dashboard > Forums > Settings > General Tab. BUT, I don't recommend it if you have other pages and content in your WordPress website. This option disables the whole WordPress pages on front-end. Only forum content will be available no other pages, no other front-end plugins.
