I tend to receive the following error message when I view the site in IE 9:

HTML1524: Invalid DOCTYPE. The shortest valid doctype is "<!DOCTYPE html>".
activate.html, line 1 character 1
SEC7113: CSS was ignored due to mime type mismatch
style.css

I include herewith the html code:

Quick summary and likely causes (two separate problems)

Both messages are real but unrelated: the HTML1524 console warning means Internet Explorer thinks the page DOCTYPE is invalid or was not seen as the page’s very first bytes (this typically happens when the page uses an XHTML/legacy DOCTYPE while being served as HTML, when there are stray bytes/comments before the DOCTYPE, or when the page triggers quirks mode). The SEC7113 message means IE refused to apply the stylesheet because the resource was not delivered as a CSS MIME type (or the CSS request returned an HTML error/redirect). See the DOCTYPE guidance and why browsers care about it, and the rules about correct Content-Type for CSS. W3C: choosing a doctype (doctype/quirks), MDN: MIME types and why text/css matters.

Practical checks (fast, in this order)

  1. Open the browser dev tools (F12) and use the Network panel. Re-load the page and inspect the request for your stylesheet: check HTTP status and the response header Content-Type. If it is not text/css or the response is a 404/500/302 that returns HTML instead of CSS, fix the server/output. 2) Check for any bytes or BOM before the DOCTYPE and remove them (save without BOM); an invisible BOM or whitespace can make IE report an invalid DOCTYPE. 3) If you’re not intentionally using real XHTML served as XML, prefer a simple HTML doctype and deliver the page as normal HTML. MDN: configuring server MIME types, TotalValidator: BOM / parsing notes.

Quick fixes to try

  • If the stylesheet’s Content-Type is wrong: add a server mapping (for Apache/Nginx add the CSS MIME, e.g. AddType text/css .css or edit your MIME map; for IIS add/edit the .css MIME type in IIS Manager or web.config).
  • If the CSS request is being redirected (login page, error page, CDN mis-route), fix the URL or the routing so the CSS returns 200 and text/css.
  • If the page has a BOM or stray characters before the DOCTYPE, re-save without BOM and validate markup. Also remember X-Content-Type-Options: nosniff will cause strict blocking when the MIME is wrong, so set the header correctly only after fixing the MIME. MDN: X-Content-Type-Options.

Notes tied to existing replies

’s suggestion to validate markup is useful — run a validator after removing any BOM/leading bytes. ’s docmode advice is relevant if IE is being forced into an older document mode. is correct that the DOCTYPE issue is the root of layout/warning problems; fixing the DOCTYPE/encoding plus ensuring the server serves text/css will clear both the warning and the SEC7113 stylesheet blockage. For a quick confirmation, fix the server so the stylesheet returns 200 with Content-Type: text/css and remove any bytes before the page’s DOCTYPE; that will resolve the problems in almost every case.

the most likely cause is IE, try a better validator, like http://validator.w3.org/check apart from messy code, hard to read, there doesnt seem much wrong

Its a 'soft warning' :: nothing to be really concerned about, - yet:
You are using a wrong doctype ( xhtml ) on a plain HTML document!
That's wrong [!] because you are missleading your current clients and also the Servers answering those requests.

But there is no harm [...] exept for
few extra (wasted) bytes on content transport, like..., 'over and over again'.
