admin web access fails, but admin/index.php is OK

I just upgraded a Omeka site for a faculty member (1.2.1 -> 1.3.2), but the admin site isn't working as it used to.

The following URL gives a 404 error:

The requested URL /cs/home/xxx/www/omeka/admin/index.php was not found on this server.

But this works:

I am try to understand why Omeka can't pickup to index.php file. Everything else works fine.
I can see index.php file and the permission are 644


Make sure you have a .htaccess file both in the root of your site and in the admin directory.

Both locations should have (different) files with exactly that name, and those files are required to make "normal" Omeka URLs work.

Thank You!!!

That fixed the problem.
