On a page mysite.com/forum I have included the WPForo. I'm able to visit that page and see an overview of my forums and posts.

But when clicking on a post to open that post, it goes to https://mysite.com/community/main-forum/testpost/#post-1. So not mysite.com/forum/.... Moreover, it there just shows an empty page. When I change the url in the browser from community to forum, I get a 404.

The same upon submitting a new post: it redirects to https://mysite.com/community/main-forum/testpost2/ where it just displays an empty page.

How can I change the url so that it uses /forum everywhere instead of /community? And what should I do so that it displays the post instead of an empty page?
