Change license site

Hi there,

I was testing the plugin WooCommerce Free Shipping Bar in my Dev Site https://devfityoumeal.wpengine.com/, all works ok.

Now I’m trying to use the plugin in my production site https://www.fityoumeals.com/ but I’m not able to use the license.

Could you please help me to achieve this?

Thanks in advance.

Best regards,

Sebastian
