Second thing check the php.ini if php_opcache extention is active
Old post https://moodle.org/mod/forum/discuss.php?d=315118
Or see in phpinfo(); :
- "session.save_path" is where php is trying to save your sessions files.
- "APACHE_RUN_USER" is the user apache is running as.
- "Loaded Configuration File" will show you which file php is reading these settings from. [also old Post]
