Hello,
I am currently using the Woo Advanced Shipment Tracking plugin in my WordPress website. Everything seem to be fine until I get to add to cart and checkout.
Adding to cart is okay, but, when I want to pay and complete my checkout, I get the error: “Error processing checkout. Please try again.”
I checked WooCommerce Log and I see this error in the log “
CRITICAL Uncaught Error: Call to undefined method WC_Email_Customer_Completed_Order::get_billing_first_name() in /var/www/wp-content/plugins/woo-advanced-shipment-tracking/includes/email-manager.php:153
“
I uninstalled this plugin and then tried to checkout and it worked perfectly. I need this plugin to work on my website. Please, can you help me figure this one out?
Thank you for your time.
