Published WP pages not be served

I have installed Wordpress in the main directory of a domain and there are 4 published pages, yet when I click on the links to those pages, I get 404 not found errors. Also, when I go to the main URL for the domain I get the default placeholder page, and not the WP page that should show up.

I tried cloning WP and putting it in a subdirectory and still get the same problems. I also checked and there are no strange aliases or redirects that would be causing this.

Thanks for any help.

Hi Amy-- It looks like the index.php file was missing from the core WordPress files. The index.php file tells the server to stop looking at the default HTML files and look at the WordPress installation. You should be good to go!
