Opera doesn't recognize body css classes
===

  I have an odd problem.  I am building a site in which there a classes in the HTML body tag.  All other browsers do as expected.  However, Opera simple won't recognize these classes.  In the source code, even in Opera, they are they.  But when I look with "Inspect Element", the only class body has is "yui-sam-skin".  I'm using Wordpress so the template is "<body <?php body_class(); ?>>

  However, I've even tried <body class="<?php if(is_front_page() ) echo "home"; ?>">.  Again, all browsers expect Opera recognize it and Opera has it in the source code, but not in Inspect Element.  Any idea what's happening here?  This doesn't happen with every site.  A site I built not long ago doesn't have this problem for some reason.  Even adding in the class with no PHP at all doesn't work.

 Thanks for any help!
