500 JHtml::cleanImageURL not found

Hi,
after update template i get error 500
JHtml::cleanImageURL not found.
This happening on articles https://jumbosnacks.gr/en/news.html

Somehow, it doesn't take the override from T4 and call it directly from Joomla core.

We updated this file on your site:

/plugins/system/t4/themes/base/html/layouts/joomla/html/image.php

Line 22:

$img = HTMLHelper::_('cleanImageURL', $displayData['src']);

change to:

use T4\Helper\Metadata;

$img = Metadata::cleanImageURL( $displayData['src']);

Thanks!
