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/php7, 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

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.
I have encountered this issue, and the permissions and ownership appear as above for the PHP session directory, and I've confirmed the directory is named as such in the PHP configuration. The resolution of setenforce 0 works, but is apparently needs to be set frequently because the permissions issue reappears. Is there a permanent solution?
Hello James,
If the disabling SELinux resolves the issue, there is possibility that the context on the /var/lib/php/session is insufficient. As far as I understood permission/ownership on directory is also got reset. The both issue require deep investigating. Please, submit request to support for further investigating. On how to do so check the article: https://support.plesk.com/hc/en-us/articles/213608509-How-to-submit-a-request-to-Plesk-support-
