checkout page Plus and minus

Hi,

That's not what I see on your checkout:

Could it be a caching issue on your browser ? Try to clear your browser's cache.
Try with another browser. Which browser are you using ?

Hi,

It seems that you selected "none" in the "frontend CSS file" setting of the HikaShop configuration page, instead of the default "default" value.
This means that the CSS HikaShop normally adds on the frontend is not added.
Instead, you've copied some of that CSS code in the file https://xn--krebsernhrung-ifb.com/templates/ducatibox/css/custom.css of your Joomla template.
However, you're missing some of the CSS code to handle the hover system of the cart module.
If you add the CSS code below in your custom CSS file, it will work properly again:

.hikashop_cart_dropdown_container {
    position: absolute;
}
.hikashop_cart_dropdown_content {
    z-index: 1000;
    position: relative;
}
