error.css X-Content-Type-Options: nosniff
« on: June 11, 2019, 04:48:05 PM »
One of my clients has been running some tests and encountered this warning:
 "... error.css” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).

The warning is right; the contents are html not css.   The functional implications are trivial but the warning is can be disconcerting for clients.

do you have an error.css file in your styles folder? I'm guessing the response was a 404 error, which is HTML.

Thanks, Bruce

You are probably right. But it leads to another question I will post separately.
