Wordpress function throwing an error

[ModernRevolutions]

Fatal error: Call to undefined function: get_header() in /homepages/31/d267335044/htdocs/layout/header.php on line 97

is showing up at the top of every page on my friend's site, here. Its not at the very top of the page but at the top of the content div. What does it mean? And how do I fix it?

I don't get any error, have you tried clearing your cache?

I removed the wordpress junk and it worked. so i accidentally fixed it. Would you mind checking and seeing if its still working fine?

Sure, I clicked around a bit and everything seems fine.
