I have followed the instructions:
1. Upload all files to to the /wp-content/plugins/bp-breadcrumb directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Call bp_breadcrumbs_add( $name, $url, $desc, $parms, $img ) in places you want to add a breadcrumb
However I cannot get the breadcrumbs to display, nothing displays when I add template tag.
