Invoice footer not working

For those who also have this issue.

Add following code at the bottom of application/views/quote_templates/pdf/InvoicePlane.php

?>
</div>

<htmlpagefooter name="footer">
    <footer>
        <?php _trans('quote'); ?> <?php echo $quote->quote_number; ?> - <?php _trans('page'); ?> {PAGENO} / {nbpg}
    </footer>
</htmlpagefooter>
<sethtmlpagefooter name="defaultFooter" value="on" />
<!-- To use the template with page numbering, uncomment the following line -->
<!-- <sethtmlpagefooter name="footerWithPageNumbers" value="on" /> -->
</body>
</html>

application/views/invoice_templates/pdf/InvoicePlane.php

</div>

<htmlpagefooter name="footer">
    <footer>
        <?php _trans('invoice'); ?> <?php echo $invoice->invoice_number; ?> - <?php _trans('page'); ?> {PAGENO} / {nbpg}
    </footer>
</htmlpagefooter>
<sethtmlpagefooter name="defaultFooter" value="on" />
<!-- To use the template with page numbering, uncomment the following line -->
<!-- <sethtmlpagefooter name="footerWithPageNumbers" value="on" /> -->
</body>
</html>

and last:

application/helpers/mpdf_helper.php

Take an extremely close look at the changes from the pull_request from naui. He made some changes in a couple of places in the mpdf_helper file

This solved the footer note (html) settng and is now back visbile on both my quotes and invoice pdf.
