error when customer trys to login

Hi,

It's because you're using the old checkout from HikaShop 1.x and 2.x, which isn't compatible with PHP 7.3.
Turn off the "checkout legacy" setting under the advanced tab of the HikaShop configuration to switch to the new checkout and it will work fine.

Hi,

This just looks like it needs a bit of CSS.
I checked your website but I couldn't find any way to access the checkout.
I went to the page vereniging-2/aanmelden-activiteiten but the products are not sold so I can't add them to the cart.
Could you provide precise instructions to access the checkout so that I could look at the situation with the CSS there ?

Hi,

You can add such CSS on your website and it will display properly:

}
.hikashop_checkout_login .hkc-sm-4 {
    width: 100% !important;
    text-align: left !important;
}
@media (min-width:768px) {
div#hikashop_checkout_registration {
    margin-left: 100px;
}
}
