Fatal error: Call to a member function get_header_logo_id() on null

Hello all,

I receive the following error when trying to create an invoice/packing slip for a received order:

Fatal error: Call to a member function get_header_logo_id() on null

/usr/www/users/compudp/pibella.co.za/wp-content/themes/x-child/woocommerce/pdf/Pibella/invoice.php (8)

#9 {main}

I have had to revert to a previous backup version of Woocommerce as updating to the latest version breaks the website, preventing me from accessing the back or front end.

Any help would be highly appreciated.

Many thanks.
