Wrong MIME type stylesheet

When viewing this blog in Firefox/Flock/Camino on MobileMe, the pages didn't display correctly. While they do display correctly when published on Personal Web Server on my Mac and on another webserver I use.

I couldn't figure out why, since the pages are the same.

Then in Flock I noticed a menu-command to display the Error console. It said the stylesheet wasn't loaded because of a wrong MIME type.

I opened the file to see what was wrong, but couln't determine. So in a hunch, I duplicated the Blog.css file that iWeb creates. Copied/pasted/renamed the Blog.css code to styles-site.css and used that file.

Now the pages display correctly.
