@metravi The plugin “Advanced Shipment Tracking for WooCommerce” caused this issue. When contacted, they mentioned that “Track Ship” moved into a separate plugin (which was once a part of “Advanced Shipment Tracking for WooCommerce”). So after installing “Track ship”, everything was back to normal. Hope this helps 🙂
Hi,
I apologize for the late reply. The problem has been fixed. It was a plugin error and a re-installation fixed it. Thanks for your help.
