Wordpress 404 Problem

[chuckie]

I have a WP blog using the Thesis theme.

It is giving the 200 Ok header when it is a 404.

It displays the 404 page, but the header says 200 Ok.

Another blog on the same server correctly gives the 404 Not Found header.

Any idea what I can check?

Thanks

Sorted. It was a plugin issue.
