You can open this file: root/templates/ja_smallbiz/html/com_content/category/xblog_item.php
At approx line 49, remove this snippet of code:
<?php if(!empty($customs['avatar'])): ?>
<span class="author-avatar">
<img src="<?php echo $customs['avatar'] ?>" alt="<?php echo $author; ?>" title="<?php echo $author; ?>" />
</span>
<?php else: ?>
<span class="author-avatar">
<img src="images/joomlart/avatar/default.png" alt="<?php echo $author; ?>" title="<?php echo $author; ?>" />
</span>
<?php endif; ?>
<span class="author-name">
<?php if ($params->get('show_author', 1)) : ?>
<?php echo JLayoutHelper::render('joomla.content.info_block.author', array('item' => $this->item, 'params' => $params, 'position' => 'above')); ?>
<?php endif; ?>
</span>
For the empty submenu under 'mnenja' menu item, you can go to Backend > Extensions > Templates > JA Smallbiz template style > click button 'Megamenu' > select item 'mnenja' and disable the option 'Submenu': http://prntscr.com/j3pnie
