OJS 3.1 (Centos 7 php 7.2)

Good day!
I installed half year ago OJS v 3.1. on OS Centos 7 php 7.2. OJS was working good. One week ago I updated the system and all modules php updated accordingly too. Now I have an error 500. Httpd log show error i files: FilterHelper.inc.php and SessionManager.inc.php. How it fix?

Please post here error messages from php error log.

Thanks

edit: and seems to be fixed here: OJS 3.1 Blank screen after installation

I was reading all this decisions before and try all of them, but it didn’t help me.

This is decision help me, but when I logged in for ‘admin’ or any others users, OJS shows me blank page
