How can I change or translate the error messages in WooCommerce Product Options?
The WooCommerce Product Options plugin displays text-based error messages to users if they make a mistake. For example, an error will appear if they try to click the 'Add to Cart' button without having selected a required option.
The error messages have been worded to be suitable for all types of business. You can translate them into other languages using a string translation plugin like Loco Translate or Translate Words. This is ideal whether you are just rewording the error messages in the same language, or translating them into another languages.
