Интеграция phpbb 3.0.10 с modx 1.0.5 #

Помогите, установил форум phpbb, установил модуль modxBB, но при добавлении кода

if (!defined('ADMIN_START'))
{
require_once($phpbb_root_path . '../modxapi.php');
}
else {
require_once($phpbb_root_path . '../../modxapi.php');
}

global $modx;
$modx = new MODxAPI();
$modx->connect();
$modx->getSettings();

в overall_header.html , выходит вот это:
Warning: include_once(/home/users1/h/haiden12/domains/stroy-masterden.ru/manager/includes/extenders/dbapi..class.inc.php) [function.include-once]: failed to open stream: No such file or directory in /home/users1/h/haiden12/domains/stroy-masterden.ru/manager/includes/document.parser.class.inc.php on line 66

Как решить проблему?
