Hello,
I am facing technical error on carrier admin settings page. If I want to edit carrier I always get alert error (image in attachment).
As I've found this technical error is because of Prestashop carrier JS admin file is using async false in AJAX request. This error does not occur in Firefox but in all chromium based (or only in chrome?) browsers because chrome since some version is blocking all async false AJAX requests.
How can I resolve this problem? I don't want to edit "core" JS file but I've found that on some other hosting servers I don't get this alert message. So maybe I have misconfigured VPS server?
Thanks
