codestyler plugin reports error in mailchimp plugin

Hi,
i have installed the code styler language plugin as recommended by woocommerce support. This plugin reports an error in the WordPress mail chimp plugin….

Loading Issue: Author is using load_textdomain instead of load_plugin_textdomain function. This may break behavior of WordPress, because some filters and actions won’t be executed anymore. Please contact the Author about that.
