• The following error is found in the log file /var/log/plesk/panel.log:

  CONFIG_TEXT: ERR [1] Exception: PHP Warning : symlink(): Permission denied; File: /usr/local/psa/admin/plib/Service/Agent/Transport/Local/Put.php, Line: 25

Cause

Plesk user psaadm is prevented to create symlinks. Refer to the CloudLinux Documentation for more details.

CloudLinux symlink protection features are not supported by Plesk.

Resolution

1. Connect to the server using SSH.

2. Open the file /etc/sysctl.conf for editing and disable the options fs.protected_symlinks_create and fs.enforce_symlinksifowner:

   # vi /etc/sysctl.conf
   .....
   fs.protected_symlinks_create = 0
   fs.enforce_symlinksifowner = 0

3. Apply the changes:

   # sysctl -p
