• Testing Challan as a potential PDF invoice generator for a client. When choosing “Download Invoice” on an order page:

    PHP message: PHP Warning:  unserialize(): Extra data starting at offset 121 of 124 bytes in /wp-content/uploads/WOO-INVOICE/mpdf/vendor/mpdf/mpdf/src/Mpdf.php on line 9051" while reading response header from upstream, request: "GET /wp-admin/admin-ajax.php?action=wpifw_generate_invoice&order_id=77210&_wpnonce=foo HTTP/2.0", upstream: "fastcgi://unix:/var/run/php8.4-fpm.sock:", referrer: "/wp-admin/admin.php?page=wc-orders&action=edit&id=77210"

    The invoice still generates, but I wanted you to be aware of this warning. Challan 3.7.85, PHP 8.4.23, WooCommerce 11.0.1, WordPress 7.0.3.

  • Hi @yardobeef

    Thank you for bringing this to our attention and for sharing the detailed error information.

    We tested Challan with the latest versions of WordPress, WooCommerce, and PHP, but we were unable to reproduce the warning on our end.

    However, we will forward your report and the provided details to our development team for further investigation. If the issue is confirmed to be related to Challan, our developers will work on a fix and include it in a future update.

    Thank you for helping us improve the plugin.
