RewriteRule (.*) example.com/$1 [R=301,L]

Answer 1

If you are redirected to another site, you need to specify "http: //" in front, otherwise Apache will interpret it as a file on the server.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.example.com [nc]
RewriteRule (.*) http://example.com/$1 [R=301,L]

Answer 2

Make sure you have www alias set in apache vhost file

<VirtualHost *>
..
ServerName www.example.com
ServerAlias example.com
...
</VirtualHost>

Also remember to restart Apache after each change.
