I've managed to update my xoops 2.5.10 version to 2.5.11. I've updated the Newbb module to version 5.1.0.b6 .
When I want to add a poll from Newbb, I get the following error :

Error: Class 'XoopsModules/Xoopspoll/Helper' not found in file /modules/newbb/polls.php line 43

use XmfRequest;
use XoopsModulesNewbb{
Helper,
TopicHandler,
ForumHandler
};
use XoopsModulesXoopspoll{
Constants as PollConstants,
Helper as PollHelper
};

/** @var TopicHandler $topicHandler */
/** @var ForumHandler $forumHandler */

// rewrite by irmtfan and zyspec to accept xoopspoll 1.4 and all old xoopspoll and umfrage versions and all clones

global $xoopsModule;

require_once __DIR__ . '/header.php';
require_once $GLOBALS['xoops']->path('class/xoopsformloader.php');
require_once $GLOBALS['xoops']->path('class/xoopslists.php');
require_once $GLOBALS['xoops']->path('kernel/block.php');
xoops_load('XoopsLocal');

$pollHelper = PollHelper::getInstance();

The last line is line 43

The xoopspoll module is installed in version 1.33.

I don't know what to correct.
thank you
