What does this error mean?

Question

[Thu Aug 25 03:26:26 2016] [error] PHP Notice:  session_start(): ps_files_cleanup_dir: opendir(/var/lib/php/session) failed: Permission denied (13) in /var/www/vhosts/site/httpdocs/qa-include/app/users.php on line 146

Priobably, you should check PHP settings by phpinfo.

• session.gc_probability (Usualy: 1)
• session.gc_divisor (Usualy: 100 /1000)

These are the settings of the starting probability of PHP garbage collection. If you are using "Debian / Ubuntu", you have to set to 0(Zero) to the gc_probability in php.ini.

Unfortunately, I still can not make the change.
I have no knowledge in SSH and I am no FTP access to my server.
It is possible to make this change by .htacess?  Or any other way?
Control panel: Plesk

Hi.

Today I noticed an important detail.

My server is CentOS 6.6

CentOS garbage collector settings might have been changed. You should report this issue to the administrator of your server.

Hello.
Update PHP can fix the problem?
