some links redirects to home page

Hi!

I have just started my forum and I love the plugin! But I don’t know why, it’s not working properly.

When I click on some forum’s links, it redirects me to home page.
Links like these:
https://www.abc.com/community/members/
https://www.abc.com/community/recent/
https://www.abc.com/community/main-forum/

But some links no problem, like these:
https://www.abc.com/community/
https://www.abc.com/community/profile/stanleychan/
https://www.abc.com/community/?type=rss2&forum=g

I suspect that it should be caused by Rewrite Rules, when I check the Rewrite Rules on my site using “Rewrite Rules Inspector” plugin, it shows: “Some rewrite rules may be missing, try flushing.”

And the missing rewrite rules only one, that is：
(community(?:/|$).*)$ index.php?page_id=26284

I try to flush rules, But nothing has changed.

How can I resovle the problem?

Thanks!
