Reply To: Problem with payment gateway

Are you sure the SHA-IN/OUT settings are correct? SHA-1 selected? As of their documentation nothing has changed and I couldn’t find any evidence that more people got that error now. But there are many discussion and things to try out if you google for “unknown order/1/s/”.

Here are a few:

they have asked me to select “Each parameters followed by pass phrase” option under Global security parameters

Go to Configuration > Technical Information > Data and Origin Verification and enter the base URL of your WooCommerce site, i.e. http://www.example.com (if your site uses SSL on the checkout page then don’t forget to include HTTPS in the url: https://www.example.com). On that same page, enter a SHA-IN pass phrase of your choosing. Then scroll to the bottom of the page and hit “Save”.

Maybe ask the ogone support if they have an idea what’s wrong.
