Dear Daniel Stołowski,
Could you please open default.php file (your site/templates/smart_news25/html/com_content/article/html/default.php), find code:
<?php if ($params->get('show_publish_date')) : ?>
<dd class="published">
<?php echo JText::sprintf('COM_CONTENT_PUBLISHED_DATE', JHTML::_('date',$this->item->publish_up, JText::_('DATE_FORMAT_LC2'))); ?>
</dd>
<?php endif; ?>
change to:
<?php if ($params->get('show_publish_date')) : ?>
<dd class="published">
<?php echo JText::sprintf('COM_CONTENT_PUBLISHED_DATE_ON', JHtml::_('date', $this->item->publish_up, JText::_('DATE_FORMAT_LC3'))); ?>
</dd>
<?php endif; ?>
Thanks
