autorefresh_notifications is not defined - Cannot navigate the BackOffice

[Guisp]

I've got this error, when ever I am on the BackOffice, sub menus dont-appear and notifications are not there. The only place where sub menus work are when i click on CATALOG, the rest of the panel is not "Updating the notifications" therefore not letting me navigate the backoffice. Here are two photos explaining this situation.
 
I also get this error: 
notifications.js:29   Uncaught ReferenceError: autorefresh_notifications is not defined(…)

 

Picture describing it, keeps loading for ever and nothing works.
 

 

When I am inside the Catalog and it loads for 1 second then everything works.

$(document).ready(function() {
	var hints = $('.translatable span.hint');
	if (youEditFieldFor)
		hints.html(hints.html() + '<br /><span class="red">' + youEditFieldFor + '</span>');

	var html = "";		
	var nb_notifs = 0;
	var wrapper_id = "";
	var type = new Array();
	
	$(".notifs").click(function(){
		var wrapper_id = $(this).parent().attr("id");

		$.post(
			"ajax.php",
			{
				"updateElementEmployee" : "1",
				"updateElementEmployeeType" : $(this).parent().attr('data-type')
			},
			function(data) {
				if (data) {
					$("#" + wrapper_id + "_value").html(0);
					$("#" + wrapper_id + "_number_wrapper").hide();
				}				
			}
		);
	});
	// call it once immediately, then use setTimeout if refresh is activated
	getPush(autorefresh_notifications);

});

function getPush(refresh)
{
	$.ajax({
		type: 'POST',
		headers: {"cache-control": "no-cache"},
		url: 'ajax.php?rand=' + new Date().getTime(),
		async: true,

This is late but looking for the answer for this exact issue and fixed it. Don't edit anything. Go in the back office and under "Performance", clear the cache. Then, clear your browser cache. 

 

Not sure why this works.

Hello,

You may disabled also your CDN cache with your provider like OVH or 1and1.

I had the same issue in PrestaShop 1.7.5.2 after migration from PrestaShop 1.6 shop in the same domain. The error was being caused by a cached version of /js/admin/notifications.js in my browser (the 1.6 version was being loaded). Clearing the browser cache fixed the issue.
