New Order Email Subject Shows Placeholders Instead of Site Title and Date Since

Overview of the Issue

If you are using WPML Multilingual & Multicurrency for WooCommerce 4.2.10, you probably noticed that new order emails are showing placeholders instead of the site title, the order number and/or the date on the Email Subject.

For example, emails are showing:

New Customer Order ({order_number}) – {order_date}

Intead of:

New Customer Order 1234 – April 23rd 2018.

Workaround

This issue will be fixed in an upcoming version of WooCommerce Multilingual.

In the meantime, you can use the following workaround:

1. Edit the class-wcml-emails.php file found in the ../woocommerce-multilingual/inc/ folder.
2. Comment out (or remove) lines 138 and 139, like shown in the following code snippet:

//add_filter( 'woocommerce_email_heading_new_order', array( $this, 'new_order_email_heading' ) );
//add_filter( 'woocommerce_email_subject_new_order', array( $this, 'new_order_email_subject' ) );
