Warning: Creating default object from empty value in capabilities.php on line 65

Hi,
The developers at https://premium.wpmudev.org/ tracked this warning down.
It was because the last line in ‘bp-usernames-only.php’ was:

add_action( 'admin_bar_menu', 'ray_wp_toolbar_title', 6 );

This replacement in ‘bp-usernames-only.php’ causes it to check if the user is logged in before trying to pull in the admin bar fix.

if ( is_user_logged_in() ) {
	add_action( 'admin_bar_menu', 'ray_wp_toolbar_title', 6 );
}

Thank you for a great and useful plugin!
