This is a multiple changing issue. If this is a new installation please delete both pages, then Uninstall wpForo (not just deactivate). Then install it again. Then create a new page "Home" (slug /site-home/). And set this page as front-page in Settings > Reading admin page. Don't make any changes with Forum page and Base URL. Also please make sure you don't have post or page with /community/ slug in Trashed section.

But I DONT want the forum to be the home page of my website!
the home page of my website should still be the "recent posts"
Then you should do nothing. Just install and find your forum under base URL. Remove the home page and reset the home page. I thought you want to make it on home.
