Hi,
all these errors are not related nor caused by WP STAGING.
These errors are caused by WooCommerce and in
I googled it and found a few links that could be helpful to you:
https://github.com/woocommerce/woocommerce-gateway-stripe/issues/2429
The message originates from WooCommerce Blocks if one of the required libraries for Checkout/Cart blocks to support payment gateways is missing. Ex: Polyfill, WC-Settings, React etc. These scripts can be de-registered by any other plugins and Stripe only comes into the error if the Stripe plugin is active. If along with Stripe, COD or Cheque is enabled – the error path will show up that as well.
I hope that helps. Otherwise, I recommend that you get in contact with woocommerce support. They should know best what these errors mean.
All the best,
René
