In item.php replace comment section with following code, I think there used to be small bug:
<!-- Comments-->
<div id="more-info" class="comments round3 i-shadow is_detail">
<?php if( osc_comments_enabled()) { ?>
<div class="item-comments">
<h2 class="sc-click">
<span><?php _e('Comments', 'veronika'); ?></span>
</h2>
<!-- LIST OF COMMENTS -->
<div id="comments" class="sc-block">
<div class="comments_list">
<div class="comment-wrap comment-empty">
<div class="ins">
<div class="comment-image tr1">
<img class="tr1" src="<?php echo osc_current_web_theme_url('images/profile-support.png'); ?>"/>
</div>
<div class="comment<?php if( osc_reg_user_post_comments () && !osc_is_web_user_logged_in() ) { ?> two-lines<?php } ?>">
<div class="body">
<span><?php _e('Question? Need more information? Want to ask question? Add new comment...', 'veronika'); ?></span>
<?php if( osc_reg_user_post_comments () && !osc_is_web_user_logged_in() ) { ?>
