Error in wdgk_modify_template

Hi there – great plugin and is exactly what we need (adding a donate button on the cart page).

The plugin works fine but is causing an issue with woocommerce-delivery-notes plugin Print Invoice & Delivery Notes for WooCommerce

When I go to preview a delivery note, instead of the delivery note I get a message “There has been a critical error on this website” but this just affects the delivery note plugin (the rest of the site works fine)

If I disable Woo Donations the error goes away.

Here is what is showing in the error logs. If you can help with this it would be much appreciated.

Many thanks
