iredadmin app is located in folder /opt/www/iredadmin, so i modified commands accordingly
You got it wrong, do not modify the commands i wrote in previous reply.
/opt/www/iredadmin (in lower cases) is a symbol link to /opt/www/iRedAdmin-0.9.4 (the version number may be different on your server), so we need to change owner/permission on iRedAdmin-0.9.4 instead, not /opt/www/iredadmin.
