Hi fafabone
To restore it you should first disable your default editor from global configuration then edit your custom module in footer-2 and add this code
<div class="info">
<img src="images/joomlart/logo/logo.png" alt=""/>
<p>
Nulla facilisi. Curabitur nibh eros, rhoncus sed risus non, bibendum posuere velit. Nunc sed interdum risus. Nulla nisi sapien, cursus et facilisis nec.
</p>
<ul class="social-list social-color">
<li><a href="#" title="Facebook" class="facebook"><span class="fa fa-facebook" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
<li><a href="#" title="Twitter" class="twitter"><span class="fa fa-twitter" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
<li><a href="#" title="Instagram" class="instagram"><span class="fa fa-instagram" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
<li><a href="#" title="Google plus" class="google-plus"><span class="fa fa-google" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
</ul>
</div>
Hope it helps
