Hello,

I have updated the theme and deactivated all the plugins, the shopping cart works properly. https://gyazo.com/cf4175a8e47fa6521688862950884ac5

Deactivate all the plugins and leave these ones only: https://gyazo.com/81260d1babe687a8460de1e4ef68972c

Then activate the plugins one by one to detect which one causes the problem.

Finally, activate the license in your theme.

If you have any questions please feel free to contact us.

Best Regards
