    Good Day

    We recently changed to WP_Mail_SMTP and also upgraded to the Latest versions.

    When we go to ‘Processing Payment’, we receive the following error in the Debug Log:

    [29-Sep-2022 12:49:55 UTC] PHP Notice: Undefined variable: trigger_hook in /home/lilyblu2/public_html/wp/wp-content/plugins/woocommerce-jetpack/includes/emails/class-wc-email-wcj-custom.php on line 132

    I have:
    Version 5.6.6 of the Free version of Booster for WooCommerce
    WP_Mail_SMTP Version 3.5.2
    Storefront Theme

    All other e-mails are working fine (i.e. New Account registered, Customer notes etc.)

    Can you assist?

    Many Thanks
