I was wondering if it is possible to limit the number of posts in a forum to like 50, after which point the oldest posts get replaced by the newest?

I understood up until

after which point the oldest posts get replaced by the newest?

I expect you can limit a forum to only show the latest 50 topics, come back if that is what you want

Yes, that is pretty much it. My explanation was more wordy than it needed be. :-\

something like

function rew_max_shown ($args) {
$args['max_num_pages'] = 2 ;
return $args ;
}

add_filter ('bbp_before_has_topics_parse_args', 'rew_max_shown') ; 

in your functions file

Functions files and child themes – explained !
