Empty Cart Prestashop Bug on Google Chrome and Mobile Browsers

In web development using Prestashop, i found a bug that i wasn't able add an item to cart, thus the shopping cart was empty. The bug only appeared on Google Chrome and mobile browsers. I used Prestashop version 1.5

The issue was on the shop's URL. i put "www" prefix in front of Shop's URL . To fix this bug follow these steps.

1. Go to admin page > Preferences > SEO & URLs.

2. Remove "www" from "Shop domain" and "SSL domain" (in case it was enabled).

3. Save setting

Enjoy!
