Why javascript has been disabled ?

I used the following code in the header.php , with the new wordpress update, this code no longer works
Why? What should I do?
this code for , site.com to nullrefer.com/?site.com
Disabling the LiteSpeed Cache plugin solves the problem
LiteSpeed Cache Why is it broken?

<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script>
$(function(){
    $('a').each(function() {
						 var str = this.href;
						 var n = str.search("arzunkadeh.com");
						 if(n == -1){
        $(this).attr('href', 'https://nullrefer.com/?' + this.href);}
    });
		   
});
</script>
