Hello @piggy811,
Thanks a lot for reaching out us. We are really sorry to see that you have faced such issue. It seems like a plugin conflict but just to be sure will you please confirm that you are not using phpqrcode library in any other plugin? We are using phpqrcode library in our plugin to generate the qr code. You can debug the error by disabling all the plugins except WooCommerce and WooCommerce QR Codes and enable them one by one to check which plugin is conflicting with our WooCommerce QR Codes plugin.
Looking forward to your co-operation regarding the same.
Regards,
Bappa
