History of crawls, escaped_fragment in url, how to remove?

Question

css

Hello, the webmaster got into Yandex to look at the updated function and what I saw there, in the history of bypasses by the Yandex bot.



What is this (escaped_fragment)?
I’ve already read something related to ajax, but I don’t have ajax pages on the page, there was background parallax and I removed it, I rummaged through all the code, I didn’t find anything, at the very bottom of the site there is a Yandex api map, it shows traffic jams, it is on all pages maybe because of her?

Scripts that I connect to the site along with Yandex api maps.
$this->template->scripts[] = ' ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.... ';
$this->template->scripts[] = 'media/js/frontend/modernizr.custom.js';
$this->template->scripts[] = 'media/js/frontend/jquery.placeholder.min.js';
$this->template->scripts[] = 'media/js/frontend/cnt.share.js';

<script type="text/javascript">$(document).ready(function(){
$(window).scroll(function () {if ($(this).scrollTop() > 0) {$('#scroller').fadeIn();} else {$('#scroller').fadeOut();}});
$('#scroller').click(function () {$('body,html').animate({scrollTop: 0}, 400); return false;});
});</script>
