I don't recommend it, but if you insist, find this section of code, and add // before the $db->Execute line as shown:
Code:
function after_process() {
global $insert_id, $db;
// update OSH records for this order
$sql = "UPDATE ".TABLE_ORDERS_STATUS_HISTORY. "
SET comments = concat(if (trim(comments) != '', concat(trim(comments), '\n\n'), ''),
'Transaction ID: :transID " .
(isset($this->responsedata['PPREF']) ? "\nPPRef: " . $this->responsedata['PPREF'] : "") .
(isset($this->responsedata['AUTHCODE'])? "\nAuthCode: " . $this->responsedata['AUTHCODE'] : "").
"\nPayment Type: :pmtType " .
"\nTimestamp: :pmtTime " .
"\nPayment Status: :pmtStatus " .
" :AVS " .
"\nAmount: :orderAmt ')
WHERE orders_id = ".(int)$insert_id;
$sql = $db->bindVars($sql, ':transID', $this->transaction_id, 'noquotestring');
$sql = $db->bindVars($sql, ':pmtType', $this->payment_type, 'noquotestring');
$sql = $db->bindVars($sql, ':pmtTime', $this->payment_time, 'noquotestring');
$sql = $db->bindVars($sql, ':pmtStatus', $this->payment_status, 'noquotestring');
$sql = $db->bindVars($sql, ':AVS', ($this->avs != 'N/A' ? "\nAVS Code: ".$this->avs."\nCVV2 Code: ".$this->cvv2 : ''), 'noquotestring');
$sql = $db->bindVars($sql, ':orderAmt', $this->amt, 'noquotestring');
// $db->Execute($sql);
