php notices on functions that do not exist

When using this shortcode setup: [bsp-display-forum-index forum= ‘47657, 47661, 47659′ search=’no’ breadcrumb=’no’] we get PHP errors on the search and breadcrumb parameter because the filters return ‘no function’.

Changing:

		if (!empty( $attr['breadcrumb']) && ($attr['breadcrumb'] == 'no' ) ) {
			add_filter ('bbp_no_breadcrumb', 'asc_no_breadcrumb');
		}

		if (!empty( $attr['search']) && ($attr['search'] == 'no' ) ) {
			add_filter ('bbp_allow_search', 'asc_no_search');
		}

to

		if (!empty( $attr['breadcrumb']) && ($attr['breadcrumb'] == 'no' ) ) {
			add_filter ('bbp_no_breadcrumb', '__return_false');
		}

		if (!empty( $attr['search']) && ($attr['search'] == 'no' ) ) {
			add_filter ('bbp_allow_search', '__return_false');
		}

resolves this issue because it calls the core WP versions to return a false.

If you have a Github repository I’m happy to provide a patch.
