It is fixed, they added a setting to the dashboard page of the payment gateway where you can enable adding the QR code to each of the woocommerce emails, and if you do not enable it for a specific email than this overwrites the settings and the PDF invoice doesn’t get attached. It looks like this:

Best regards,

I have found the cause, the plugin “F4 QR Rechnungen für WooCommerce” is causing it. I will contact them.

Thanks for the help.

I have searched our custom code for wpo_wcpdf assuming that code that interferes with it would use an action hook that is named like that. And the only thing I found is this:

add_action('wpo_wcpdf_custom_styles', function($type, $order_document) {
  if ($type === 'invoice') {
    ?>
    .qr-invoice-page {
      page-break-before: always !important;
    }
    <?php
  }
}, 99, 2);

And just now a new order went in with a different payment method and the PDF is attached:

Hi Yordan, Thank you for the answer.

We have no PDF invoice activated for “Order Completed”. But I made a test order to trigger the admin email and there is no error and no PDF invoice is attached.

I also don’t think we have any PHP code enabled to interfere with this, but I will take a look there.

I have a similar problem and I can confirm it.

I use the woocommerce_after_checkout_validation hook to validate some checkout data and a call to wc_add_notice('XXX', 'error') interrupts the checkout process but the error is not displayed.

I solved this.. I just use

add_action('woocommerce_product_query', 'filter_express_versand_products');

instead of

add_filter( 'pre_get_posts', 'filter_express_versand_products' );

and now it works as it should

Hello,

I can reproduce it like this:

First add meta values to variable products:

add_action('wp', function() {
  add_post_meta(228, "example", rand(1,999));
  add_post_meta(209, "example", rand(1,999));
});

Code to filter products in archive:

function filter_express_versand_products( $query ) {

  if (is_archive() && isset($_GET["example"]) && $_GET["example"] === "1") {

    $meta_query_args = array(
      'meta_query' => array(
          array(
            'key' => 'example',
            'value'   => '',
            'compare' => '!='
          )
      )
    );
    $query->set('meta_query', $meta_query_args);
  }
  return $query;
}
add_filter( 'pre_get_posts', 'filter_express_versand_products' );

Delete all transients with WP-CLI:

wp transient delete --all

Open the filtered archive /shop/?example=1

After that, all variable products with these meta values are broken.
