Questions:

I’m using Quick.gallery (http://quick.gallery) script on my website but I’m getting some erros with Firebug:

When I try to access http://www.portaloficial.com.br/fotos.php, Firebug show me some erros like “js=js_viewer was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).”

Can anybody help me on this?

How to&Answers:

I had this issue before, when I was referencing a mistyped URL, so the reason for content-type html was, that I actually got a HTTP 404 error page.
