If the products list is reloaded each time you display a page with a products list then you can fix this by modifying the file /warehouse/modules/ps_shoppingcart/ps_shoppingcart.js as follow:

How to fix warehouse theme

Replace this line:

prestashop.emit('updateFacets', window.location.href);


if (event.reason && event.reason.linkAction != 'refresh') {
    prestashop.emit('updateFacets', window.location.href);

When the cache is created, the page is anonymized, that means it is displayed without any information about the visitor displaying the page.

Modules that display content relative to the current visitor can be marked as dynamic, that means the content will be refreshed (replaced) by a background request (Ajax) in the browser that will carry the context of the current visitor.

If you check the option "Display nothing in cache" then the module will not be called to display its content in this hook during the creation of the cache. However, the content will be displayed as other dynamic modules (with a background request (Ajax)).

To avoid the cookie notice to appear 1 second, then disappear, you must override the javascript file of the iqitcookielaw module.

To do it, create a file with the following content:

$(document).ready(function () {
 if (getCookie('cookielaw_module') != 1) {
 $("#iqitcookielaw-accept").click(function (event) {

function setcook() {
 var name = 'cookielaw_module';
 var value = '1';
 var today = new Date();
 var expire = new Date();
 expire.setTime(today.getTime() + 3600000 * 24 * 14);
 document.cookie = name + "=" + escape(value) + ";path=/;" + ((expire == null) ? "" : ("; expires=" + expire.toGMTString()))

function getCookie(cname) {
 var name = cname + "=";
 var ca = document.cookie.split(';');
 for (var i = 0; i != ca.length; i++) {
  var c = ca[i];
  while (c.charAt(0) == ' ') c = c.substring(1);
  if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
 return "";

And place it in the theme (or child theme if you have one): /themes/warehouse/modules/iqitcookielaw/views/js/front.js

Then clear the cache in the Performances page.

To get your styles back you just need to clear the cache of "Page Cache Ultimate".

To avoid this issue you can go in "Advanced mode", in the configuration of "Page Cache Ultimate", then in "Cache key" enable "Insert CSS and JS version in cache key".

No, it is highly recommended to keep the Smarty cache enabled. This will speed up pages that are not cached and also pages where the cache is not yet generated.

If you are using Nginx, then make sure your configuration is as follow:

Nginx configuration for Speed Pack module

"Proxy mode" must be ON, other options must be OFF.

If your theme uses the tag "widgetblock" as Warehouse theme does, then you need to clear the cache in Performances page after you enable Page Cache so the template is compiled again.

If you have an Anvato theme, here is what to do to avoid the cart to open each time it is refreshed.

Copy the file /modules/an_theme/views/js/sidebarcart.js in your theme so you can continue to update it without loosing modifications, in /themes/<your_theme>/modules/an_theme/views/js (create folders if needed)

In this file, replace the ligne:

if ( != 'cart' && != 'checkout') {


if ( != 'cart' && != 'checkout' && requestData.action!='refresh') {

Then clear the cache in Performances page and the cache of your browser so you can test.

These fake users are created by Page Cache Ultimate to anonymize the cache (new method). You must not delete them (they will be created again).

There will not have a lot of these fake users, probably less than 5, it depends on the number of groups and the differences in display between them.

They are not active so they will not disturb your statistics.

This is the desktop view, to see the adapted view you must reload the page!
