Title: Document Data not showing after WordPress Update Last modified: November 11, 2022 --- # Document Data not showing after WordPress Update * Resolved [samd2020](https://wordpress.org/support/users/samd2020/) * (@samd2020) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/) * Hi, * We just updated our wordpress version to the latest wordpress as well as the latest version of the pdf invocie & packing slip plugin. However the “PDF document data” tab on the order pages is now empty. * Also when I look under the PDF invoices settings, even with the “simple” template, on the right hand side it is saying: * “Document not available for order #39070, try selecting a different order.” – data does exist for this order however. * Any help would be appreciated. * Thank you, * Sam Viewing 7 replies - 1 through 7 (of 7 total) * Thread Starter [samd2020](https://wordpress.org/support/users/samd2020/) * (@samd2020) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16188143) * Also, on the right hand column there is still a “pdf packing slip” option and when we click on this it throws the following error: * ``` Fatal error: Call to undefined function Dompdf\mb_internal_encoding() /home/(insert site here)/public_html/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/vendor/dompdf/dompdf/src/Dompdf.php (295) #0 /home/(insert site here)/public_html/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/vendor/dompdf/dompdf/src/Dompdf.php(269): Dompdf\Dompdf->setPhpConfig() #1 /home/(insert site here)/public_html/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/class-wcpdf-pdf-maker.php(48): Dompdf\Dompdf->__construct(Object(Dompdf\Options)) #2 /home/(insert site here)/public_html/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/documents/abstract-wcpdf-order-document.php(799): WPO\WC\PDF_Invoices\PDF_Maker->output() #3 /home/(insert site here)/public_html/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/documents/abstract-wcpdf-order-document.php(864): WPO\WC\PDF_Invoices\Documents\Order_Document->get_pdf() #4 /home/(insert site here)/public_html/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/class-wcpdf-main.php(401): WPO\WC\PDF_Invoices\Documents\Order_Document->output_pdf('inline') #5 /home/(insert site here)/public_html/wp-includes/class-wp-hook.php(308): WPO\WC\PDF_Invoices\Main->generate_pdf_ajax('') #6 /home/(insert site here)/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters('', Array) #7 /home/(insert site here)/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #8 /home/(insert site here)/public_html/wp-admin/admin-ajax.php(188): do_action('wp_ajax_generat...') #9 {main} ``` * Plugin Contributor [Yordan Soares](https://wordpress.org/support/users/yordansoares/) * (@yordansoares) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16189418) * Hi [@samd2020](https://wordpress.org/support/users/samd2020/), * Could you send us a screenshot of your **System Configuration** and **Write Permissions**, that you’ll find under **WooCommerce > PDF Invoices > Status** tab? * You can use imgbb.com to upload the screenshot, and then share the image URL here. * Thread Starter [samd2020](https://wordpress.org/support/users/samd2020/) * (@samd2020) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16192724) * Hi Yordan, thank you please see this link: * [https://ibb.co/HzW5gZz](https://ibb.co/HzW5gZz) * Plugin Contributor [Yordan Soares](https://wordpress.org/support/users/yordansoares/) * (@yordansoares) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16196529) * Hi [@samd2020](https://wordpress.org/support/users/samd2020/), * Thanks for providing that screenshot. This explains why you’re receiving that error: Your sever doesn’t have the `mbstring` PHP extension activated. Please ask your hosting provider to activate it, and then try opening a PDF document to check if it’s generating correctly. * Thread Starter [samd2020](https://wordpress.org/support/users/samd2020/) * (@samd2020) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16198704) * Hi Yordan, * Thank you the mbstring extension has been activated and the packing slip is now working. * Unfortunately the pdf invoice section on the customer order page still isn’t working properly though. Here is how it looks on the page: [https://ibb.co/mB8znm3](https://ibb.co/mB8znm3) * Under the plugin settings page general settings when choosing a template (even with the simple template), the section to the right still says “Document not available for order #39097, try selecting a different order.” * Here is the staus page now: [https://ibb.co/gFjyy0W](https://ibb.co/gFjyy0W) * Thanks for your help * Plugin Contributor [Yordan Soares](https://wordpress.org/support/users/yordansoares/) * (@yordansoares) * [3 years, 7 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16200525) * Hi [@samd2020](https://wordpress.org/support/users/samd2020/), * Could you please check if you have the PDF invoice and/or PDF packing slip activated, under **WooCommerce > PDF Invoices > Documents > Invoice/Packing Slip**? * Plugin Contributor [Yordan Soares](https://wordpress.org/support/users/yordansoares/) * (@yordansoares) * [3 years, 6 months ago](https://wordpress.org/support/topic/document-data-not-showing-after-wordpress-update/#post-16256073) * Hi [@samd2020](https://wordpress.org/support/users/samd2020/), * Since we haven’t heard back from you in the last two weeks, we’re assuming you solved this issue, so I’ll go ahead and mark this ticket as **Resolved**. * Feel free to reply to this topic is you still need help with this, or [open a new topic](https://wordpress.org/support/plugin/woocommerce-pdf-invoices-packing-slips/#new-topic-0) if you have any other questions!
