Good evening! I have a strange issue with hikashop cart module. At first the strange thing it's that the price in minicart is wrong, is not the price like in the checkout cart so I've tried to disable the mini-cart option. The price now is changed but if I try to avtivate the mini cart and try to save this choice it return to "no" automatically. Any sueggestion?

Goodmorning and thanks for the answer. I've tried to activate debug mode and change the php error reporting level but nothing. When I try to change some option in hikashop cart module there isn't error messages but everything come back to a specific setting. Can I try to install Hikashop again? I'll lose all the products that I've created? thanks again!

The problem was Firefox. I've tried in Chrome and everything is fine.
