The ErrorLog will not relocate to <VirtualHost>

In spite of having the error logfile for a <VirtualHost> within its container, its host's errors will be logged at ErrorLog /var/log/apache2/error.log rather than in
/var/log/ispconfig/httpd/domain/error.log as provided in the .vhost

I have tried usual fixes like changing property of the folders and file...... nothing worked.

 

all folders are root/root chmod 755
the error.log is client1/web4 chmod 664

ErrorLog /var/log/ispconfig/httpd/airpatrol.us/error.log

The addition is red which is mod_perl2
I have manually added /perl/ directory
The error is generated by the mod_per test script /perl/x.pl

However, it appears that the errors generated by the script /cgi-bin/x.pl are properly relocated.

Code:

<Directory /var/www/airpatrol.us>
    AllowOverride None
    Order Deny,Allow
    Deny from all
</Directory>

<VirtualHost *:80>
      DocumentRoot /var/www/airpatrol.us/web
  
    ServerName airpatrol.us

There is another twist to this.
It appears that an error generated by a script executed in /perl/x.pl will properly relocate.

However, if that script includes a modul.pm (mod_perl module) and if the error happens within that module it will not relocate and goes to /var/log/apache2/error.log

So I do not know if the ISPConfig 3 supports mod_per2 or if it is normal but there is nothing in the apache2.conf which would distinguish between a script and module generated errors.
