Dear Claudeir Ribeiro,
We fixed that issue, please check your site again.
Fixed: Go to the file: /public_html/optimus/templates/sj_univer/html/com_k2/templates/default/item.php and add the code:
<?php if($this->item->numOfComments>0 && $this->item->params->get('itemComments') && ($this->item->params->get('comments') == '1' || ($this->item->params->get('comments') == '2'))): ?>
<!-- Item user comments -->
<h3 class="itemCommentsCounter">
<span><?php echo $this->item->numOfComments; ?></span> <?php echo ($this->item->numOfComments>1) ? JText::_('K2_COMMENTS') : JText::_('K2_COMMENT'); ?>
</h3>
<ul class="itemCommentsList">
<?php foreach ($this->item->comments as $key=>$comment): ?>
<li class="<?php echo ($key%2) ? "odd" : "even"; echo (!$this->item->created_by_alias && $comment->userID==$this->item->created_by) ? " authorResponse" : ""; echo($comment->published) ? '':' unpublishedComment'; ?>">
<span class="commentLink">

<img src="<?php echo $comment->userImage; ?>" alt="<?php echo JFilterOutput::cleanText($comment->userName); ?>" width="<?php echo $this->item->params->get('commenterImgWidth'); ?>" />
<?php endif; ?>
<span class="commentDate">

<a class="modal" rel="{handler:'iframe',size:{x:560,y:480}}" href="<?php echo JRoute::_('index.php?option=com_k2&view=comments&task=report&commentID='.$comment->id)?>"><?php echo JText::_('K2_REPORT')?></a>
<?php endif; ?>
<?php if($comment->reportUserLink): ?>
<a class="k2ReportUserButton" href="<?php echo $comment->reportUserLink; ?>"><?php echo JText::_('K2_FLAG_AS_SPAMMER'); ?></a>
