Has anyone seen this issue? I'm seeing this on a test intranet website.

When I'm not logged in, I just see the raw content with no css. Once I log in, the site /pages look normal. I dont see the same issue on the production version of the site. The test version was recently copied from the production (db and content) .

Hello Tom: 

It sounds like the file isn't available for some reason.  If you're able to see the full path in the HTML source, I'd suggest trying to load it directly and/or using the web dev console to inspect for any HTTP errors and other clues. In some cases, you may even be able to turn on debugging to determine if a rewrite rule or something else is getting in the way.  

My experience is usually a typo or firewall/rewrite issue.

Hi Will - 

Thanks for your response! 

I did look in the console and there are multiple css pages that don't load due to this error:

http://sccintranettest/AD...dule.css%3fcdv%3d395 was not loaded because its MIME type, “text/html”, is not “text/css”.

The code and database are identical to our proiduction site, which doesn't show the issue, except for the web(dot)config. Maybe the issue is in the web(dot)config.

Any idea? thanks - 

Tom

Well, in the case of a HTTP 404 error, the response itself is indeed text/html, so I wouldn't worry about that too much (yet).  I'd first suggest tracking down what's making it seem like the file isn't there.
