Hello folks,

Strage: i'm getting this error after install TeamSpeak Server on my VPS...?!

The following errors are displayed in the /var/log/sw-cp-server/error_log

I allready red the thread about this problem after an update (500 Error after automatic micro-update - Plesk 10.4) but i have two problems:
1) I'm using Plesk Panel Version 11.0.9
2) I'm using Ubuntu 10.04

And now... do i have to reinstall the packages? Or anything other?

Please help me fast.... =(

Could you please show output of command:

ls -la /usr/lib/sw-cp-server/sw-suexec

it should be like

-rws--x--- 1 root sw-cp-server 354661 2011-06-22 11:40 /usr/lib/sw-cp-server/sw-suexec

if it's not, then set permissions by

chmod 4710 /usr/lib/sw-cp-server/sw-suexec
