How do I disable plesk error messages?

[kavukattu]

When there is a Plesk error (ERROR: PleskFatalException), how can I disable the stack trace which contains sensitive information that is visible to any public user? For instance:

ERROR: PleskFatalException


Command not found: "Xx<XaXaXXaXaX>xX

--------------------------------------------------------------------------------

0: /usr/local/psa/admin/plib/common_func.php3:156
psaerror(string 'Command not found: "Xx<XaXaXXaXaX>xX')
1: /usr/local/psa/admin/htdocs/get_password.php:179

Is there a flag I can configure in a Plesk configuration file somewhere?

I'm running Plesk 8.2 on FC6.

Thanks!
