Cannot complete checkout

[ablears]

In Version 2.9.0 I'm unable to check out on one of my staging sites.

I see about 50 of these warnings in the logs when I select a payment method and try to complete checkout:

PHP Warning: A non-numeric value encountered in /var/www/xx/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/mpdf.php on line 30591

Strangely I do get the order email with PDF invoice attached, but checkout errors with an empty WooCommerce error box and doesn't redirect to the order received page.

Hi,

You can try version 2.9.1 which should fix this issue. Let me know if it works.
