    Hi, sorry for the trouble.

    Pls update the following line of code in the /wp-content/plugins/wc-fields-factory/includes/wcff_order_handler.php

    Replace the Line No 57 with the following.

    $template = "single-product";
if (WC()->session) { 
    $template = WC()->session->get("wcff_current_template", "single-product");
}

    This has already been applied to the latest release, right?

    Yes it is now, I have a silent update (without changing the plugin vertsion).

    Prior to Version 4 we haven’t used WC session object on order handler, but version Version 4 has some dependency on the WC session.

    In a normal order flow the wc session will be available in the order handler module, since it is from the cart -> checkout page.

    But here the subcription will happens in an arbitrary (as per schedule) time and the order will be prepared from the parent order, not from the cart object, hence no session.

    Anyway now the condition has been included before accessing WC Session in order handler.

    Yes, the fix is available with the latest version, I just did a silent update (without changing the version).

    From Version 4.X order handler is using WC session for some features, this is not an issue if the order is normal flow (Cart -> Checkout -> Order) since WC session will be there.

    In the case subscription the order will be arbitrary (as per schedule) and there won’t be Wc session, since subscription order will be created from a corresponding parent order (not from WC Cart) hence this issue.

    Now I have added condition for checking WC session.

    @sarkware thanks for the info, have made the change.

    Curious – why a silent update instead of a new bugfix version?

    Hi,
    At that time it was only one reported issue.
    So I thought instead of new version, silent update would do, but after that there are coulpe of issues, so that I had to release new update(s).
