Forbidden You don't have permission to access /vhosts/ehcp/index.php on this server.

Hi,

i just have a wondrous problem, when i browseing website on ehcp server sudnly i encounter this error an all websites on the server:

Forbidden

You don't have permission to access /vhosts/ehcp/index.php on this server.

here is the log file:
root@ehcp:~# tail -f /var/log/apache2/error.log
sh: /ps: No such file or directory
sh: /ps: No such file or directory
sh: /ps: No such file or directory
sh: /ps: No such file or directory

[Thu Jan 28 12:37:54 2010] [error] [client 18.28.10.24] client denied by server configuration: /var/www/vhosts/ehcp/index.php, referer: http://10.19.25.124/vhosts/ehcp/index.php?op=adddomain

what is this problem anymore?

sh: /ps: No such file or directory

that means shell script sh trying to access some file in /ps, but cannot access.
Did you put anything special to your server ?
some script on your server may be doing something nasty.

"You don't have permission to access /vhosts/ehcp/index.php on this server" this means, some configuration on your server has changed, .htaccess file for ex.

I suggest you to empty your apache config and debug your system as described in http://ehcp.net/?q=node/771#comment-1177
