1option Hi
As I can see that you put the code which renders tags correctly:
<?php if ($info == 0 && $params->get('show_tags', 1) && !empty($this->item->tags->itemTags)) : ?>
<?php $this->item->tagLayout = new FileLayout('joomla.content.tags'); ?>
<?php echo $this->item->tagLayout->render($this->item->tags->itemTags); ?>
<?php endif; ?>
is there any cache settings on your server side?
