@yogthos As far as I can tell, those assets can't be found on Internet Explorer or Edge browsers.

the way the assets are pulled is browser agnostic

the assets are served exactly the same way as any other asset from resources/public folder would be served

When I access my luminus site from IE or Edge, I get nearly a hundred errors in the console like this: HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier). The URIs are all things like this: (XHR)GET - which, when I look them up, all appear to be associated with bootstrap. I'm not using sass or scss or bootstrap other than what's included in the base template, so I find this rather mysterious.
