Crontabmng error after migration

GPDCenter

New Pleskian
Hi all,

we successfully migrated web and email from a Plesk 9.3 system to the new Plesk 12.0 system.
Afterwards i try to install new extensions and / or try to delete existing extensions and receive the following error

Die Erweiterung Webserver Configurations Troubleshooter kann nicht entfernt werden: crontabmng failed: /usr/bin/crontab execution failed: "crontabViWP46":11: bad command errors in crontab file, can't install. System error: crontab execution error

Means that i am not able to delete the extension "Webserver Configurations Troubleshooter". But the extension is delete (but not completelly - only a checkbox is shown without entry).

Is something comes with a config of the old server? All works proper until migration.

Thanks in advance for your help
 
You will need to open the crontab file with
Code:
crontab -e
and in it find any bad commands and either put a # before them or delete them.
