Google reading pages as 404

Hi guys,

can anyone help me out here as im going crazy. We created some new subapages a while back.

First we named it without "php" then with, but still the same problem.

example
http://www.freebetsmarket.co.uk/online-betting.php
http://www.freebetsmarket.co.uk/online-betting/

When i submit these pages to Digg or Browser shots it comes back as a 404, and now Google has indexed these new pages, it's listing them all as 404.

Any ideas why these pages are being read wrong?

Thanks
Les

 

the first link is working....refresh your page once

 

I get a 404 for both of them. Anything else in the webserver's error logs?

 

I'm getting a 404 as well. The most obvious answer is that the pages haven't uploaded to the server but I'm going to assume you have checked that

Something in the .htaccess file causing problems?

Pages in the wrong directory?
