bbPress.org

it could be a theme or plugin issue

Themes

As a test switch to a default theme such as twentytwenty, and see if this fixes.

Plugins

If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

If you cannot do this to your site (say because it is live) then use the ‘troubleshooting’ features of this plugin to let you test without affecting other users

Then come back

thanks, just tested with just bbpress and agree it does disappear.

I had bbp private groups enabled, although no settings affecting, but with this it shows.

I’ll try and take a look tomorrow (10pm in UK at the moment) to see what private groups does that is fixing that !

ok, I’ve found time to take an initial look at this.

The function called looks at a database item which holds the sub forum count – but it looks like this is just count of public forums, so the count is zero, so none displayed.

so removing looking at this takes away the issue.

It would take a deal of work to see why and how to make a permanent fix to this, and I think this filter will do what you want

add_filter('bbp_forum_get_subforums', 'rew_forum_get_subforums', 10, 3);

function rew_forum_get_subforums( $sub_forums, $r, $args ) {

	// Default return value
	$retval = array();
	
	// Use passed integer as post_parent
	if ( is_numeric( $args ) && ! empty( $args ) ) {
		$args = array( 'post_parent' => bbp_get_forum_id( $args ) );
	}

	// Parse arguments against default values
	$r = bbp_parse_args( $args, array(
		'post_parent'         => 0,
		'post_type'           => bbp_get_forum_post_type(),
		'posts_per_page'      => get_option( '_bbp_forums_per_page', 50 ),
		'orderby'             => 'menu_order title',
		'order'               => 'ASC',
		'ignore_sticky_posts' => true,
		'no_found_rows'       => true
	), 'forum_get_subforums' );

	// Ensure post_parent is properly set
	$r['post_parent'] = bbp_get_forum_id( $r['post_parent'] );
	
	
	// Query if post_parent has subforums
	if ( ! empty( $r['post_parent'] )  ) {
		$get_posts = new WP_Query();
		$retval    = $get_posts->query( $r );
	}
	// Filter & return
	return (array) apply_filters( 'rew_forum_get_subforums', $retval, $r, $args );
	
}

Put this in your child theme’s function file –

ie wp-content/themes/%your-theme-name%/functions.php

where %your-theme-name% is the name of your theme

or use
