Hi there,
I see what you mean, but the issue is from the script itself.
https://mylush.net/js/tp.js
Its code is this
document.write("<a href='http://mylush.net' title='לוח ×©× ×”'>×™×•× ×¨×שון, ×™\"ב שבט ×”'תשע\"×—, 28/01/2018, פרשת השבוע: יתרו</a>")
The code itself doesn’t add target="_blank"
, but you may add your code like this
<script language="JavaScript" src="https://mylush.net/js/tp.js">
</script>
<script type="text/javascript">
jQuery( document ).ready( function($) {
$('a[href="http://mylush.net"]').attr('target', '_blank');
} );
</script>
Hope this helps.
