bbPress.org

Thanks Pippin. Justin Tadlock gave me same advice to go into that file. Let me tell you that it’s little out of my head. But I definitely try this out and report here if I find a solution.

$query->set( 'meta_key', '_bbp_last_active_time' );
$query->set( 'orderby', 'meta_value' );

This actually works better because now sticky posts are in their ‘natural’ position, not last.
