Can you put this before the DOCTYPE in the forum header:

<?xml version="1.0" encoding="utf-8"?>

Since it’s xhtml, not xhtml transitional like the blog, maybe that will do the trick?

edit: on my server this resulted in a parse error, maybe because the <? is being interpreted as php? This might not be a good idea
