Hello,
This path can be controlled in the index.php from this coding.
<div class="s5_logo_wrap">
<center>
<img alt="logo" src="<?php echo $s5_directory_path ?>/images/s5_logo_dark.png" class="s5_logo" onclick="window.document.location.href='<?php echo $LiveSiteUrl ?>'" />
</center>
</div>
By default this URL will echo your live site URL to redirect users to the Home Page. You can also use a Custom HTML module in the logo position with some HTML onclick custom coding to redirect it as well if you are familiar with HTML.
