Using Wamp, new pages get 404 "requested URL not found on this server"

Hi
I am running Wamp. Each time I create a new static page, the link appears on the menu bar of my homepage but, when clicked om, the new page can’t be found.

I created a page called More with sample text, clicked on the link on my homepage and a got the message:

Not Found

The requested URL /wordpress/more/ was not found on this server.

The preview was fine but once published, any new page comes up with a 404 error.

I’m new to WordPress and would appreciate any help.

Thanks

Brian
