We'll create fresh WordPress site with WP-UserOnline installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin enables you to display how many users are online on your WordPress site, with detailed statistics of where they are and who they are (Members/Guests/Search Bots).
WP-Admin -> Appearance -> Widgets
wp-content/themes/<YOUR THEME NAME>/sidebar.php
and add Anywhere:<?php if (function_exists('users_online')): ?>
<p>Users online: <div id="useronline-count"><?php users_online(); ?></div></p>
<?php endif; ?>

I spent most of my free time creating, updating, maintaining and supporting these plugins, if you really love my plugins and could spare me a couple of bucks, I will really appreciate it. If not feel free to use it without any obligations.
