My page used to validate as of a day or two ago. I don't think that I've changed anything along the way, but I could be wrong, but now my page won't validate because it says it doesn't have a DOCTYPE header, though I clearly see one both in the source and in the actual file. I've modified my index.php quite a bit, but I've double and triple checked it against the default one from WP and it's the same. It's not invalidating my page and defaulting to html 4.01 instead of xhtml 1.0 transitional. Any ideas? My site is at http://www.aqueerlife.com.
