Opencart Payment gateway error after opencart 2.0 upgrade - php

Question

We have a payment gateway called atom for our opencart store. Recently we have upgraded Opencart from 1.5.6.4 to 2.0.1.0 version. Due to this payment method stopped working. I have gone through this post to understand the changes in opencart 2.0
Below is my updated code
//catalog/controller/payment/atompay.php
<?php
class ControllerPaymentAtompay extends Controller {
protected function index() {
$this->language->load('payment/atompay');
$data['button_confirm'] = $this->language->get('button_confirm');

$this->session->data['order_id'];
if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/payment/atompay.tpl')) {
return $this->load->view($this->config->get('config_template') . '/template/payment/atompay.tpl', $data);
} else {

And

<?php

if ($this->config->get('atompay_total') > $total) {
$status = false;
} elseif (!$this->config->get('atompay_geo_zone_id')) {
$status = true;
} elseif ($query->num_rows) {
$status = true;
} else {
$status = false;
}
$method_data = array();
if ($status) {
$method_data = array(
'code' => 'atompay',
'title' => $this->language->get('text_title'),
'terms' => '',
'sort_order' => $this->config->get('atompay_sort_order')
);
}
return $method_data;
}
}
?>
When i try to make an order confirm order is disabled and there are no error logs found. Am i missing something?

Your index() method is defined with protected access. So you are unable to call it from outside its scope. So you should change it to public function index().
