Hello,

I'm getting errors in the console:

Access to XMLHttpRequest at 
'https://www.codeblackbelt.com/json/preferences/currency-converter-plus.json?countryCode=US&shop=blue-dream.myshopify.com&activeCurrencyCode=USD&path=%2Fproducts%2Fsoldier'
 from origin 'https://eshop-hub.com' has been blocked by CORS policy: No
 'Access-Control-Allow-Origin' header is present on the requested 
resource.

Failed to load resource: net::ERR_FAILED

The interesting part is that I don't remember to had "Currency Converter Plus" installed on my site. Any ideas how to remove it's js code? And how it is installed on my site?

Thanks
