I'm using WordPress 2.6.2 and my 404 page is having some issues.
A page that doesn't exist:
The result is that the URL is the page title and the contents of it is source code starting at my sidenav running to the end.
I have never seen the 404 page up until now so I'm not 100% sure if it has ever worked. Has anyone seen anything similar? I've checked through the posts here but it's hard to explain so I may have missed something.
