One-Page Checkout [Support Thread]

[njcyx]

Sorry, one more warning. We received an order using paypalwpp. The delivery address somehow was blank (hopefully only intermitent). We also received the following warning from OPC.

[12-May-2026 10:59:16 America/New_York] PHP Fatal error: Uncaught Error: Undefined constant "EMAIL_GREET_NONE" in /includes/modules/checkout_one_send_welcome_email.php:22

Line 22 is the following

$email_text = sprintf(EMAIL_GREET_NONE, $firstname);

Update. It seems to be not related to paypalwpp. We received another normal order using paypaldp. It shows the delivery address as normal, but I receive the same warning.
