User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

on desktop - I opened in anonymous window https://sk.factcool.com/muzi/muzi-oblecenie/tricka-panske and when I want to click on product image , I am not redirected to product page.
It works in firefox in nonanonymous mode and even in other browsers.
It is not working even in firefox for ios (nonanonymous mode).

Actual results:

nothing

Expected results:

redirected to product page

I can reproduce this issue when Strict mode (Option > Privacy & Security > Content Blocking) or on Private Browsing window.

I see this in strict mode in the console:

Exponea [Wed, 08 Apr 2020 01:26:12 GMT] Missing Google Analytics SDK (window.ga is not defined). Either integrate Google Analytics with your website or disable Google Analytics integration in the SDK config:
https://docs.exponea.com/docs/config-object exponea.min.js:30:260

Sure enough, if I unblock and shim the request to https://www.google-analytics.com/analytics.js (even if it's an empty script), that seems to be enough to un-break the page.

The page appears to have fixed this recently, as I'm not longer seeing the error I saw in comment 2, and clicking on product images works.
