Cause
The permissions for PHP session directory are incorrect or directory does not exist.
Resolution
-
Log in to Plesk and check the current
session.save_pathfor domain in Domains > example.com > PHP Settings.Note: On Ubuntu or Debian, if
session.save_pathis not set, then session files are saved in /var/lib/php5, on RHEL and CentOS systems, ifsession.save_pathis not set, session files will be saved in /var/lib/php/session. -
Connect to the server via SSH and make sure the directory exists and have proper permissions (1733). If path is
/var/lib/php/session:# stat /var/lib/php/session | grep Access
Access: (1733/drwx-wx-wt) Uid: ( 0/ root) Gid: ( 0/ root)If directory does not exists create it and set valid permissions:
# mkdir -p /var/lib/php/session && chmod 1733 /var/lib/php/session
If directory exists but permissions are different, set the correct ones:
# chmod 1733 /var/lib/php/session
Note: If the issue persists, disable SELinux:
# setenforce 0

I am suffering from the same issue and I use CentOs system. I cross check session.save_path through phpinfo(); it shows /var/lib/php/session.
I rest the permissions for it but still the issue is active. please help me to resolve it.
@Soni, check the permissions and ownership of the folder:
# ls -ld /var/lib/php/session
drwx-wx-wt 2 root root 4096 Nov 6 00:32 /var/lib/php/session
Permission should be 1733
Should it be session or sessions? In centos it is session. Above you have sessions?
Hi @Justin Lnch,
Ubuntu, Debian - /var/lib/php/sessions/
CentOS - /var/lib/php/session/
Your answers here helps me, but i have added the directory given inside SFTP root not on the FTP and it resolved my issues. Thanks so much guys, i hope this input also helps others
Hi,
I am using Suse 12, And there is /var/lib/php7 folder but no session folder is there so should i create a new session directory and set permission to 1733.
Please help me.
