I ran into all kinds of issues with php 7.1.
A bunch of stuff doesnt work with it yet.

I would try version 7.0.16.

That was the latest version that would work with everything for me.

try

in bbpress 2.5.12 change line 1800 from

if ( empty( $post_stati ) ) {
            $post_stati = (array) bbp_get_public_status_id();

I got the same error with bbPres 2.5.13 when I switched from PHP 7.0 to 7.1 (and HTTP error 500 on the forum page).
Afaik this problem is fixed in bbPress 2.6. My advice: Switch back to PHP 7.0 until the update for bbPress has arrived.
