404 Errors relating to plugin coookies

Hi,

Thank you for the great plugin!

I am testing the free version of the plugin and hope to make it available to my customers in a week or two. While checking my server records, the file

/wp-content/plugins/refer-a-friend-for-woocommerce-by-wpgens/public/js/cookie.min.js?ver=1.3.0

has generated over 55,239 404 errors.

It doesn’t look normal to me. Is my installation that created the problem? Is this normal?

Thanks again!
