 * Hi there,
 * Some users on our site are unable to purchase products — when they try, the product
   page just reloads.
 * While troubleshooting, we found this in `debug.log`:
   `[26-Jul-2025 06:15:53 UTC]
   PHP Warning: Undefined array key "line_subtotal" in /wp-content/plugins/deposits-
   partial-payments-for-woocommerce/includes/class-awcdp-front-end.php on line 856`
 * We’re using:
   – Deposits & Partial Payments for WooCommerce v1.2.2– WooCommerce
   v10.0.4– PHP 8.2.29– Divi theme (latest version)
 * Not sure if the warning is related to the issue, as we’re still testing, but 
   wanted to report it just in case.
 * Thanks in advance!
