PHP Code:
$find = '<div>' . "\r\n\t\t\t\t" . '<p>' ;
$replace = " <!-- Refresh Button -->\n";
if ($vbulletin->options['active_users_onoff'])
$replace .= '<button onclick="showUsers()" type="button" style="float:left;"> ' . htmlspecialchars_uni($vbphrase['refresh_button']) . '</button>' . '<div id="thread_active_users">' . "\n" . ' <p>';
// $replace .= $find;
$vbulletin->templatecache['SHOWTHREAD'] = str_replace($find, $replace, $vbulletin->templatecache['SHOWTHREAD']);
