Thank you. Yes – that was the issue. Out of date custom templates.

I’m getting the same error message:

Fatal error: Call to a member function is_allowed() on wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/wcpdf-functions.php (81)

This is when trying to generate the PDF from the admin – in a single order.

The issue arose after bringing WP and plugins up-to-date last week. Previously it worked as expected.

I have a similar problem, but it’s just a select field which is not updating – or rather it’s using the first option, regardless of which option is selected. Textfields, checkboxes are all updating fine, as expected.
