Resolved PHP session.save_path issue after dist-upgrade

[Izaim]

Hello,
Recently I've been seeing issues with the php session path after upgrading from Ubuntu 14 to 16. Could not login on different scripts like WHMCS, Blesta etc.

The issue was with the session.save_path, in Xenial the PHP5 is replaced with PHP7 and the directory "php5" does not exist in "/var/lib/php5" anymore where Plesk keeps PHP sessions temporary by default, but "/var/lib/php" does exist instead. (check below)

What is your Plesk version? This behavior was fixed in Plesk 12.5 - https://kb.plesk.com/en/128190
Have you tried solution from this article? Does it help?

Sorry I forgot to mention, my Plesk version is Onyx, I upgraded from 12.5 .

Bumping this old thread as I have noticed a very similar problem with Plesk Obsidian 18.0.30.1 after a recent upgrade from Debian Jessie to Stretch.

On a website running a PHP version installed by Plesk, users couldn't login anymore. Turned out the "session.save_path" was still set to "/var/lib/php5/sessions" although PHP 5 had been removed with the upgrade to Stretch.

Solution was to fix this in "/opt/plesk/php/*/etc/php.ini" by setting

session.save_path = "/var/lib/php/sessions"

and then running

plesk repair web -v -php-fpm-configuration
