  • Plesk 11.0 for Linux


When you try to change admin password through Plesk, the following error appears:

Error: Unable to change the administrator's password: ch_owner failed: file does not exist or is not executable: /usr/local/psa/admin/bin/ch_owner


  1. Permissions are not correct for /usr/local/psa/admin/bin/ch_owner.

  2. 'fs.enforce_symlinksifowner' is set to 1 by default. It effectively disables ability to run Plesk's wrapper.

    # grep sym /etc/sysctl.conf
    fs.enforce_symlinksifowner = 1
    fs.symlinkown_gid = 503


  1. Check permissions for mentioned file, they should look as below:

    # ll /usr/local/psa/admin/bin/ch_owner
    lrwxrwxrwx 1 psaadm psaadm 15 Dec 26 15:22 /usr/local/psa/admin/bin/ch_owner -> ../sbin/wrapper
  2. Disable 'fs.enforce_symlinksifowner' (setting it to "0"):

    # grep sym /etc/sysctl.conf
    fs.enforce_symlinksifowner = 0
    fs.symlinkown_gid = 503
