Hi,

Try to add the following code snippet to the Custom CSS area in Theme Settings to fix this issue.

body.dropdowns-color-light .cart-widget-side {
	background-color: white;
}

body.dropdowns-color-light .cart-widget-side .widget-close,
body.dropdowns-color-light .cart-widget-side .remove,
body.dropdowns-color-light .cart-widget-side .total strong,
body.dropdowns-color-light .cart-widget-side .product-title,
body.dropdowns-color-light .cart-widget-side .empty{
	color: #2d2a2a;
}

body.dropdowns-color-light .cart-widget-side .empty:before,{
	color: rgba(135,135,135,.15);
}

body.dropdowns-color-light .cart-widget-side .empty:after {
	color: #858585;
}

body.dropdowns-color-light .cart-widget-side .amount {
	color: #282d4f;
}

body.dropdowns-color-light .cart-widget-side .quantity {
	color: #bbb;
}

body.dropdowns-color-light .cart-widget-side .widget-close:before,
body.dropdowns-color-light .cart-widget-side .widget-close:after {
	background-color: black;
}

body.dropdowns-color-light .cart-widget-side .widget-title {
	color: black;
}

body.dropdowns-color-light .cart-widget-side .total,
body.dropdowns-color-light .cart-widget-side .widget-heading {
  border-color: rgba(129,129,129,.2);
}

body.dropdowns-color-light .cart-widget-side .widget_shopping_cart .mini_cart_item:hover {
	background-color: #f9f9f9;
}

body.dropdowns-color-light .cart-widget-side .mini_cart_item:hover .product-title {
	color: #333;
}
