    $data['orderDetails'] = $this->model_checkout_order->getOrder($this->session->data['order_id']);
    $data['ordertax'] = $this->model_checkout_order->gettax($this->session->data['order_id']);
    $data['orderProduct'] = $this->model_checkout_order->getOrderProduct($this->session->data['order_id']);
    $this->response->setOutput($this->load->view('default/template/common/success.tpl', $data));

Array to string conversion.

This error you get when you try to echo the array value in PHP. You cannot use the array as a string!!

To overcome this issue you can add key to the array you want to print.

For example.

<?php $orderDetails[0]['order_id'];?>

This will return the value of order_id in $orderDetails array at the key of 0. It is recommended you use for loop to get the values from the array as you cannot be sure how many keys will be there.

Good Luck!!
