Hello,

There is a bug in bb-includes/functions.bb-forums.php, at line 101 in bbpress v1.0.2. The code assumes that the forum_id is the sames the array_id when the array is flattened. This is not always the case if you apply_filters to the forum list such as private forums does.

The code ccurrently reads:

_forums[$_id] = $forums[$_id]

Which may not be true if the forum id is not the same as the array id.

This code does fixed the problem…. The key is to convert forum_id into an array enumerator so that when you look at $_ids you compare to the proper array which is no longer the full array but one with missing topics/forums.

$forums = (array) apply_filters( ‘get_forums’, $forums );

+ foreach($forums as $f) {

+ $fids[$f->forum_id] = $f;

+ }

if ( $child_of || $hierarchical || $depth ) {

$_forums = bb_get_forums_hierarchical( $child_of, $depth, $forums );

if ( !is_array( $_forums ) )

return false;

$_forums = (array) bb_flatten_array( $_forums, $cut_branch );

foreach ( array_keys($_forums) as $_id )

+ $_forums[$_id] = $fids[$_id];
