To remove that section, you have to perform template override on this file: JoomlaFolder/components/com_komento/themes/wireframe/structure/default.php
Remove this part of the code :xwxwxwx
<div class="o-empty">
<div class="o-empty__content">
<i class="o-empty__icon fa fa-comments-o"></i>
<div class="o-empty__text t-lg-mt--md"><?php echo JText::_('COM_KOMENTO_NO_COMMENTS_POSTED_YET'); ?></div>
</div>
</div>
and the ‘no comments posted’ section will be gone.
