Payment gateway development

Hi,

The payment gateway I am developing is not redirecting the user to the gateway payment form. It was working with earlier versions of woocommerce and I suspect the following line is causing the issue –

add_action(‘woocommerce_receipt_mygateway’, array($this, ‘receipt_page’));

Please advise what may be the solution, I am receiving the following error

{“result”:”failure”,”messages”:”
\n\t\t\t
We were unable to process your order, please try again.<\/li>\n\t<\/ul>\n”,”refresh”:”true”,”reload”:”false”}

Thanks

Anurag
