Problem in automatic changing status

Hello, I saw in the log file that the return is trying to update the status to “processing”, but It always take into consideration the order #0. It’s not returning the correct order number, as you can see in the log example bellow.

01-14-2015 @ 01:28:29 - Updating to processing the status of the order #0

What should I do to fix this problem?

Thanks!

Cara, ele não passa o código do pedido corretamente, por isso a confirmação não é processada no WooCommerce.

Eu alterei na linha 540 do arquivo class-wc-cobregratis-gateway.php:

ANTES ERA:
$order = new WC_Order( $order_id );

COMO FICOU:
$order = new WC_Order( $data['document_number'] );

Que bom que deu certo!
Na época tentei falar com o criador do plugin, mas ele não retornou.
