Hi
As I remembered, I fixed this issue last week for you: https://www.joomlart.com/forums/d/44133-category-list-error-attempt-to-modify-property-params-on-null
Did you remove it?
I updated this file again: /templates/ja_teline_v/html/com_content/category/default_articles.php
Line 222 - 227:
<?php if ($article->publish_down != null && (strtotime($article->publish_down) < strtotime(JFactory::getDate()))
&& !in_array($article->publish_down, array('',JFactory::getDbo()->getNullDate()))) : ?>
<span class="list-published label label-warning">
<?php echo Text::_('JEXPIRED'); ?>
</span>
<?php endif; ?>
Kindly check.
