                $status_objects = $this->get_status_objects($user_id);

                foreach ( $status_objects as $status ) {?>
                    <div class="status_item">
    Line 134 ----->  <?php $user = $this->load_user_object($status->user_id); ?>
                        <h3><a href="/social/profile-view.php?uid=<?php echo $user->ID; ?>"><?php echo $user->user_nicename; ?></a></h3>

    just change user_id to user_ID . don't forget php is case sensitive

    change line 134 to

    <?php $user = $this->load_user_object($status->user_ID); ?>
