kouliga But, please could you tell what was the problem? And how to add title and href ??
As you can see from documentation your social module is using the addthis script
To add your socials settings you should create your own account on addthis website and then assign to your social channels from addthis dashboard the respective urls.
After your settings added to addthis dashboard you should copy your own code into social module
<script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid=ra-523d4894767843b5"></script>
pubid=ra-523d4894767843b5 this code identify your account on addthis website
