Enable cart only for registered users

Solved!

Just added the code on style.css, whit this code can hide the cart.

#wrap_all .sub_menu {
display:none;
}

.woocommerce-message {
display:none;
}

.thumbnail_container div.thumbnail_container_inner a.product_type_variable,
.thumbnail_container div.thumbnail_container_inner a.product_type_simple {
display:none;
}

.quantity {
display:none;
}

.summary button {
display:none;
}

.cart_dropdown {
display:none;
}
