What do you have on the mentioned line (1882) ?

function fn_promotion_shippings($this, $cart) line 1882
{
$result = false;
if ($this['operator'] == 'eq') {
$result = false;
} elseif ($this['operator'] == 'neq') {
$result = true;
}

$this is a reserved word in PHP.. Suggest you change

$this to $promotion_condition in the function parameters and in the function body.

I'm going to guess this was a bug specific to your cs-cart version and a test case didn't exist for shipping promotions.

In my 4.7.1 local installation this function has the following code

function fn_promotion_shippings($promotion_condition, $cart)
{
    $result = false;

if ($promotion_condition['operator'] == 'eq') {
    $result = false;
} elseif ($promotion_condition['operator'] == 'neq') {
    $result = true;
}


if (!empty($cart['chosen_shipping'])) {
    foreach ($cart['chosen_shipping'] as $id) {
        if ($promotion_condition['operator'] == 'eq' && $id == $promotion_condition['value']) {
            $result = true;
        } elseif ($promotion_condition['operator'] == 'neq' && $id != $promotion_condition['value']) {
            $result = false;
        }
    }
}


return $result;



}

Try to replace function code and check the result
