Hi!
I've added code with Russian social buttons in K2 Settings
<script type="text/javascript" src="//yastatic.net/share/share.js" charset="utf-8"></script><div class="yashare-auto-init" data-yashareL10n="ru" data-yashareType="button" data-yashareQuickServices="vkontakte,facebook,twitter,odnoklassniki,moimir,lj,friendfeed,moikrug,gplus,surfingbird"></div>
In category option to show social buttons: ShareThis, AddThis is on.

derka.pickupguild.ru/index.php/obuchenie/programmy-obucheniya/programma-start

Could you help me, what I am doing wrong.
Regards, Peter.
