I'm seeing the same thing on mine. Looks like they were in the middle of refactoring getcss() to xoops_getcss(), change that back in XOOPS_ROOT\header.php to revert so it sort-of works. My setup still has a bad home page, but I'm not going to worry about it until the next CVS update (shows menu, login, blocks, but not formatted).
On the positive side, I VERY much like the new administrative section. Nice job!
