roundcube and php problem

Hi,

I followed this http://www.howtoforge.com/using-roundcube-webmail-with-ispconfig-3-on-debian-wheezy-apache2, to install roundcube on debian 7, ispconfig 3.0.5.3. After I finished with installation, source code of index.php was shown on http://site/webmail. To test php, I create file /var/lib/roundcube/test.php

Code:

<?php
phpinfo();
?>

and got empty page when I open it http://site/webmail/test.php.
Php is working Ok on main site. I guess I have misconfigured system. Any suggestion what to check next?

 

how about the error log from the site?

 

I don't see any errors in apache errorl.log.

 

you do know that every vhost you create got his own error log?

And look if error_reporting is on

 

Yes, I also checked vhost log, nothing in there also, this is from vhost access.log

Code:

127.0.0.1 - - "GET /webmail/test.php HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0"
