[OJS 3.1.2-1] PHP warning

Software Support
1

My server:
PHP: 7.3.7-1
Apache/2.4.38 (Debian)
10.4.6-MariaDB-1:10.4.6+maria~buster
Goodnight! Tell me please. Is it possible to completely remove these warnings from Apache2 logs? Can you tell? I would be very grateful.
PS I really want to understand this system (OJS).

You can suppress the PHP notice and warning and deprecated messages in your php configuration . In a production environment, you probably want to suppress the following:

error_reporting=E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE & ~E_WARNING
