i've ubuntu server with virtualmin installed, i set up a vhost for my website, but when i access

http://intranetip/~test1/phpinfo.php , it print out

<? echo phpinfo ?> and another site print blank page and view source code you can see <? echo phpinfo ?>

but when i put it in /var/www/html , it can print the phpinfo

After searched in google and tried several answer, still not work.
