I have used the menu item type as - "
K2 » Latest items from (one or more) users or categories". However in this particular menu's page, Ratings are not shown, I have Ratings checked as Show everywhere.

Hello santosh,

These settings are for the category items, not the latest items. (You must have a menu pointing towards K2 Categories).

You can however try pasting the snippet in your latest_item.php.

Remember to use overrides and do not edit core files.

[code type=php-brief] <!-- Item Rating -->
<div class="catItemRatingBlock">
<span><?php echo JText::_('K2_RATE_THIS_ITEM'); ?></span>
<div class="itemRatingForm">
<ul class="itemRatingList">
<li class="itemCurrentRating" id="itemCurrentRating<?php echo $this->item->id; ?>" style="width:<?php echo $this->item->votingPercentage; ?>%;"></li>
<li><a href="#" rel="<?php echo $this->item->id; ?>" title="<?php echo JText::_('K2_1_STAR_OUT_OF_5'); ?>" class="one-star">1</a></li>
<li><a href="#" rel="<?php echo $this->item->id; ?>" title="<?php echo JText::_('K2_2_STARS_OUT_OF_5'); ?>" class="two-stars">2</a></li>
<li><a href="#" rel="<?php echo $this->item->id; ?>" title="<?php echo JText::_('K2_3_STARS_OUT_OF_5'); ?>" class="three-stars">3</a></li>
<li><a href="#" rel="<?php echo $this->item->id; ?>" title="<?php echo JText::_('K2_4_STARS_OUT_OF_5'); ?>" class="four-stars">4</a></li>
