Invoice & Delivery Note are both completely blank

try to deactivate all plugin except woocommerce and woocommerce delivery notes. does it work then?

I turned all plugins off and on, and reinstalled the WordPress core files, because the site had other issues too. Now everything works. Not sure what happened there – some kind of file corruption after updating WooCommerce? ANYWAY, it’s all good now. Thanks.

Hello,

Since the latest updates of WooCommerce, invoice, delivery note or receipt are no longer displayed and it is no longer possible to print them.

For example when I click on “preview”, the invoice is displayed half a second and then a blank page with a “0” appears.

If I look at the URL, during the second half I can see:
“…/wp-admin/admin-ajax.php?print-order=8401&print-order-type=invoice&action=print_order”
and then it continues to load and it becomes: “…/wp-admin/admin-ajax.php?dasya=true” and the page turns blank and displays only a “0”.

When I try to print invoices the same thing happens.

All my plugins have been updated, I do not encounter another error.
I tried to disable all plugins, but it does not change anything.

What can I do?

Thank you

I found this :

Error Return Values
If the Ajax request fails in wp-admin/admin-ajax.php, the response will be -1 or 0, depending on the reason for the failure. Additionally, if the request succeeds, but the Ajax action does not match a WordPress hook defined with add_action(‘wp_ajax_(action)’, …) or add_action(‘wp_ajax_nopriv_(action)’, …), then admin-ajax.php will respond 0.

So do you know how to resolve this?

Thank you

Hi thanks for the nice plugin.
It worked fine – but I have the same problem with printing the invoice.

If my customer receives an email and press on “Open print view in browser” this link shows up:

https://print-invoice/1990/?print-order-type=invoice&print-order-email=

that can’t be right?!?

thanks in advance
