XMLHttpRequest cannot load https://static.hupso.com/share/buttons/PinExt.png. No

`XMLHttpRequest cannot load https://static.hupso.com/share/buttons/PinExt.png. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://www.pillbox-websitedesign.co.za’ is therefore not allowed access.

As far as I know this issue is due to your server configuration. The resources have not been explicitly set to allow cross domain access.

Any idea why this is the case? Thanks
