    I recently noticed a problem. When choosing Klarna as payment option in the checkout process, this returns a “Something went wrong” message (loaded from the Klarna system). This error messages shows:

    Sorry for any inconvenience, please try reloading the checkout page or try again later.

    If the problem persists it maybe be because you are using an old version of the web browser which is not safe nor compatible with modern web sites. For a smoother checkout experience, please install a newer browser.

    There’s an option “Reload checkout”, but as far as I can tell this does not resolve the problem. Tested on newest version of Chrome + Firefox.

    In the server logs, we consistently see the message:
    “Missing WC session kco_wc_order_id during update Klarna order sequence.”

    The WooCommerce session is missing kco_wc_order_id during checkout initialization. We think this issue started after updating WooCommerce to version 9.8.x, and we do know WooCommerce 9.7 (and later) introduced stricter session handling, especially for checkout/cart endpoints.

    Klarna Checkout currently appears to rely on legacy session management (_legacy: true) which is not fully compatible with the latest WooCommerce session model.

    When the Klarna iframe fails to initialize, the front-end shows the error I mentioned above. No issues were caused by security headers, caching has been excluded correctly, and standard troubleshooting has been performed.

    Hello! Thank you for your question! We checked your website and could not see this error, the checkout seems to load correctly. Could you please confirm if this has been resolved on your side as well?

    Kind regards,

    We are still seeing the error.

    It works on mobile, but not on desktop (3 browsers have been tested, all up to date).
