Console errors regarding social icons request.

Hi there,

Currently working on issue that is preventing the website to redirect to HTTPS,
and it appears to be caused by the following error in the browser console.

Unsafe attempt to load URL https://mysite.com/wp-content/plugins/simple-social-icons/symbol-defs.svg#social-facebook from frame with URL http://sharpconfidentman.com/. Domains, protocols and ports must match.

Deactivating the plugin doesn’t prevent the error being thrown and it seems the attempt is coming from the theme.

Can you please advise on what might be the cause/fix?

Many thanks.
