I upgraded to 4.0.2. I confirmed it works but there is one small tweak that needs to be made.
For iTrader Navbar Link plugin:
Code:
$template_hook[$this->registry->options['itrader_postbit_location']] .= '<div class="userinfo_extra">' . $vbphrase['itrader_feedback_score'] . ': <a title="' . $vbphrase['itrader_total_feedback'] . '" href="' . $this->registry->options['bburl'] . '/itrader.php?' . $session['sessionurl'] . 'u=' . $this->post['userid'] . '">' . $this->post['itrader_total'] . '</a> ' . $vbphrase['itrader_feedback_reviews'] . $this->post['addition'] . '</div>';
I had to add class="userinfo_extra" to the <div> HTML so it would display correctly. Otherwise, one user's feedback score was appearing next to their avatar.
