HTTP ERROR 500 when loading the login page

I am using
Dolibarr 12.0.4
PHP 7.4
MySQL or MariaDB 5.6.42-lo
on Apache/2.4.43 (Unix)

After installing the last version, when I try to load he login page I get HTTP ERROR 500. On my server I have found this problem:

PHP Fatal error: Uncaught Exception: Missing log handler file mod_syslog_chromephp.php in /mnt/web001/d2/70/56878970/htdocs/dolibarr/htdocs/core/class/conf.class.php:736

Any solution? Thanks!
