I've enabled the feature that lets you use custom permalinks in wp.
I chose mywebsite.co.uk/%year%/%postname%/
Now, I'm trying to edit the permalink on the about us page.
So I typed in mywebsite.co.uk/2011/about-us/
but it saved as mywebsite.co.uk/2011about-us/ and when you click 'about us' on the home page it says
The requested URL /2011about-us/ was not found on this server.
Can anyone explain why this is happenning and what I should change?
