    Hi, when I download a customer invoice I get a the wordpress critical error, this is the error log that’s showing

    simplehygienesolutions.co.uk [Thu Feb 11 13:28:44 2021] [error] [client 86.11.212.153:0] AH01071: Got error ‘PHP message: PHP Fatal error: Cannot declare class HTML5_Data, because the name is already in use in /public_html/wp-content/plugins/print-invoices-packing-slip-labels-for-woocommerce/includes/vendor/dompdf/lib/html5lib/Data.php on line 5’
