jQuery only works when I'm logged in

Hi,

I am using GP premium to add Hooks to a website. In the specific I have small script in the wp_head and usually I use the same on other projects and it always works.

I realised that the script is loaded only when I am logged in WordPress.

I try to deactivate all the plugins (security and cache plugins etc.) but is not solving the problem.

This is the script:

<script>
jQuery(document).ready(function($){
$(document.body).on("mouseenter mouseleave", ".kg-1", function() {
$('.w_01').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-2", function() {
$('.w_02').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-3", function() {
$('.w_03').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-4", function() {
$('.w_04').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-5", function() {
$('.w_05').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-6", function() {
$('.w_06').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-7", function() {
$('.w_07').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-8", function() {
$('.w_08').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-9", function() {
$('.w_09').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-10", function() {
$('.w_10').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-11", function() {
$('.w_11').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-12", function() {
$('.w_12').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-13", function() {
$('.w_13').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-14", function() {
$('.w_14').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-15", function() {
$('.w_15').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-16", function() {
$('.w_16').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-17", function() {
$('.w_17').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-18", function() {
$('.w_18').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-19", function() {
$('.w_19').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-20", function() {
$('.w_20').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-21", function() {
$('.w_21').toggle();
});

$(document.body).on("mouseenter mouseleave", ".kg-22", function() {
$('.w_22').toggle();
});
	
});
</script>

Thats the error I get when I am not logged in:

Uncaught ReferenceError: jQuery is not defined at (index):61

Do you have any tips?

Thanks in advance!!!
