You're getting a 404 on the stylesheet: onedaylaterindex.php?/serendipity.css
is not found. Could be the index.tpl, if you've made any modifications to it; could be the "Relative Path" in admin->Configuration->Paths. It looks like you've got Serendipity installed in your root directory, so this should be "/".
You get 404 errors all over the blog.
Even the article links do not work and the paths look strange.
Seems it has something to do with the URL forming and the relative paths you have set in your configuration.
Try to disable the URL rewriting and check your paths settings please.
thanks guys... It was both of your suggestions. I must have changed it accidentally on some crap machine in China for some reason, then forgot to change it back
