Thanks for the quick reply. I just tested it again, this time with a vanilla wordpress installation with only the latest woocommerce and the latest “Print Invoice & Delivery Notes for WooCommerce” installed. I’m also using the latest php version. If I buy something in my test store with the email address [email protected] this is the Link the “Print” button on the thank-you page will point to:
https://testshop.example.com/my-account/print-order/321/[email protected]
Opening this link just shows an empty page. If I replace the “+” sign with a the proper escape sequence, it works:
https://testshop.example.com/my-account/print-order/321/?print-order-email=test%[email protected]
Let me know if you need more info.
