Hi guys,
Upon loading the page I get this [Error]: Failed to load resource: the server responded with a status of 404 (Not Found) (cs-head.js.map, line 0)
http://example.com/wp-content/themes/pro/cornerstone/assets/dist/js/site/cs-head.js.map
Any idea what this is? I tested it, so I know that it does not relate to code under Appearance > Customise > Custom.
Thanks.
