wplogin error in error console

My login loads and works fine, but the browser detects the following error:

Error: The stylesheet http://www.mysite.com/blog/ was not loaded because its MIME type, “text/html”, is not “text/css”.
Source File: http://www.mysite.com/blog/wp-login.php
Line: 0

When I look at the source file everything looks correct. All the style sheets have text/css and the content type at the top of the header is text/html which is what it’s supposed to be. I don’t get this error on my main blog page, just on the login page.
