Hi, i had a big problem with bbpress in the sense that it crashed (fatal error) every time i tried to administrate it by clicking the “forums” tab.

I found out that the below function was the problem, and in particular that i needed to change to:
$post_stati = bbp_get_public_status_id();
from
$post_stati[] = bbp_get_public_status_id();

for some reason the straight brackets broke everything, i don’t understand why, so i wanted to flag this for future updates. i’m a complete newb so yeah 😀

error code:

I’ve now gotten my forum to work by commenting the entire thing and putting

function bbp_pre_get_posts_normalize_forum_visibility( $posts_query = null ) {
    return;
}

would this have fatal influences on other aspects?

It sounds like you might be using PHP 7?

If indeed that is the case the issue you are having I think is fixed in bbPress 2.6-beta

You can update (and test) the new bbPress https://bbpress.org/forums/topic/bbpress-2-6-beta-1/
