WooCommerce Checkout integratie | WordPress.org

Your theme has this CSS code that hides “labels”, and the checkbox is wrapped in a label:

.floating-labels .form-row > label:not(.woocommerce-form__label-for-checkbox):not(.checkbox) {
display: none;
}

You can overwrite this by adding some custom CSS code to your site:

.mc4wp-checkbox-woocommerce label {
display: block !important;
}

Many themes will have a place to add custom css, somewhere under Appearance > Customize > Additional CSS. Otherwise you can use a plugin like “Simple custom CSS” to add this code to your site.

Hope that helps. If you have any questions, please let me know!
