cant connect to chrooted ssh

[LoïcM]

chrootsh permission denied

with plesk 10.4 on ubuntu
when i connect to myserver with a chrooted user i've got this error :
/opt/psa/bin/chrootsh: Permission denied

if i change the shell (/bin/bash) there is no problème.
Anyone have an idea please ?

as i saw in another post i ran this command

sh -x /opt/psa/bin/chrootsh

here is the output

/opt/psa/bin/chrootsh: 1: Syntax error: ";" unexpected (expecting ")")
