TZ Portfolio is giving errors on frontend and backend - "JArrayHelper" not found

it seams o be some kind of isue due to joomla 3.5 and jommla 4.0.

Changes i've made to workaround the problems . . .

On file "components/com_tz_portfolio_plus/addons/content/navigation/models/article.php"

Line 142 -> $scatid = ArrayHelper::getColumn($row->second_categories, 'id');
Line 160 -> if ($app->isClient('site') && $app->getLanguageFilter())

on the admin site "components/com_tz_portfolio_plus/addons/mediatype/image_gallery/tmpl/default.php"

Line 47 -> if ($japp->isClient('admin')) {

Hi,

To my knowledge the Joomla 4.2.8 and TZ Portfolio 2.6.3 are the latest versions. Am I missing something ?

backoffice log:

An error has occurred.

Hi, first, you should update all the addons and styles of TZ Portfolio+ to the latest version.
Second, plz turn on the debug system and send me the screenshots of the error.
