Solution for this topic
Sorry to hear of the problem you are having.
I visited your shared site and found it is generating following error message in browser console causing social icons font not to load.
Access to Font at 'http://www.disneybrit.com/wp-content/themes/gillion/fonts/Simple-Line-Icons.ttf?v=2.2.2' from origin 'http://disneybrit.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://disneybrit.com' is therefore not allowed access.
Please make sure you are using same URL in your site General settings as shown in the attached screenshot.
