images are not rotating - Uncaught TypeError...

Hi,
JLex 360 couldn't run because your site load many jQuery version.
There is example code:
<script src="/plugins/system/yt/includes/admin/js/jquery.min.js" type="text/javascript"></script>
<script src="/plugins/system/yt/includes/admin/js/jquery-noconflict.js" type="text/javascript"></script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
<script src="/plugins/content/jlex360/assets/jlex360.js?v=2.1.1" type="text/javascript"></script>
<script src="/media/system/js/mootools-core.js" type="text/javascript"></script>
<script src="/media/system/js/core.js" type="text/javascript"></script>
<script src="/media/system/js/mootools-more.js" type="text/javascript"></script>
<script src="/media/system/js/modal.js" type="text/javascript"></script>
<script src="/media/jui/js/jquery.min.js" type="text/javascript"></script>

You should turn off jQuery loaded by special extension.
Good luck !

Thank you,
Is it possible to solve it with https://extensions.joomla.org/extension/jquery-easy.  Or do you know about better solution?

Yes. There is a good solution
