I was searching a answer to my problem for hours and i can't figure out what's going on.
I have w shop on Prestashop (ilashop.pl) and the latest created accounts can't add products to cart after logged in. When user isn't logged everything is working fine. I had error in console but i can't find a problem in file. I created a lot new accounts and on everyone problem is the same.
Thank you in advance for help.
