looks like your .htaccess file needed to be re-generated.
admin >> settings >> permalinks >> mod_rewrite generate .htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
i've added these rewrite rules that i think you were using, and your site seems to be working now... im not sure why that file didn't copy correctly.
also i noticed your wp-config file was never setup fully, i've never seen wordpress function without it but somehow yours works lol
define('AUTH_KEY', 'put your unique phrase here');
define('SECURE_AUTH_KEY', 'put your unique phrase here');
define('LOGGED_IN_KEY', 'put your unique phrase here');
define('NONCE_KEY', 'put your unique phrase here');
you need to enter unique phrases into those fields.
