Subdomain can't generate new config

[Corné]

OS: Ubuntu 12.04
Plesk panel: 11

When I log in on the plesk panel I see the following message:
New files of configuration for Apache web server were not built due to errors in configuration templates: . The detailed error message was e-mailed to you, so please check the e-mail, fix the errors, and click here to retry generating broken configuration or click here to retry generating of all configurations.

Clicking on "here" to retry ends up in:
Web server reconfiguration is failed with error: Execution failed. Command: httpdmng Arguments: Array ( [0] => --reconfigure-all ) Details: Empty error message from utility.

When I run the command on the commandline I receive the following message:

/usr/local/psa/admin/bin/httpdmng --reconfigure-all
2012-08-23T15:37:48+02:00 ERR (3): Apache config (13457290530.34444100) generation failed:

Execution failed.
Command: httpdmng
Arguments: Array
(
[0] => --reconfigure-domains
[1] => ( All domain names are listed here )
)

Details: Empty error message from utility.

When I perform this action on a single domain it will perfectly execute. When I do this on a subdomain it goes wrong.

Somebody an idea?

Thanks for your reply.

That results in the following error:
Class 'Template_Scheme' not found in /opt/psa/admin/plib/api-common/Httpdmng.php on line 150

So I rolled back the original package.
