Monitor and display registered users activity (logins, posts, comments, etc.). You can also track and prevent hackering attemps, with IP blacklisting.
I had to edit the file wp-act-admin.php, line 285 is throwing a warning because the $wpdb->prepare now requires 2 arguments to be passed.
$logins = $wpdb->get_results($wpdb->prepare($act_recent_sql, null));
I just added ", null" and now all seems to be well. I only use this for the admin to track login and all feed items are deactivated.
