[sync] active sync not working

[chris at dsws.biz]

Hi,
I just installed the active sync solution of Horde into a Horde 5  
Webmail System.
As soon as I open the page I get only a blank page,
In the logs I see this message:



[Mon Aug 19 20:01:00 2013] [error] [client xxx.xxx.xxx.xxx] script  
'/home/group/status.php' not found or unable to stat
[Mon Aug 19 20:01:30 2013] [error] [client xxx.xxx.xxx.xxx] script  
'/home/group/status.php' not found or unable to stat
[Mon Aug 19 20:02:00 2013] [error] [client xxx.xxx.xxx.xxx] script  
'/home/group/status.php' not found or unable to stat

This is my apache2 config:


<VirtualHost xxx.xxx.xxx.xxx:443>

I also have display error set to true and log_errors to false.
PHP is in Version 5.4.4
MariaDb in Version 5.5
OS: Debian 7
Apache2: 2.2.x

Please help
