template-›_tpl_load_file() Ошибка PHPBB

Итак, я пытаюсь создать сообщение на внешней странице на моей странице WordPress. Я пытаюсь опубликовать новую тему в определенном разделе форума. После долгих попыток поместить части posting.php из PHPBB внутрь скрипта, он у меня пока показывает страницу, но не форму шаблона публикации. Теперь это моя ошибка:

template->_tpl_load_file(): Файл /posting_body.html не существует или пуст

Я пытался добавить ./ или /forum/styles и т. д. и т. д. до этого, но ничего не работает. Я также пробовал решение этого вопроса: ошибка API шаблона phpBB, но это также не сработало.

Теперь это полный скрипт:

    define('IN_PHPBB', true);
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : './forum/';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);
include($phpbb_root_path . 'includes/functions_posting.' . $phpEx);
include($phpbb_root_path . 'includes/functions_display.' . $phpEx);
include($phpbb_root_path . 'includes/message_parser.' . $phpEx);
