Resolved error_log not in expected but unknown location

[Sebastian]

When creating new subdomains, the log folder
/var/www/vhosts/domain.com/logs/subdomain.domain.com
is created, but is missing the PHP error_log file, so we can't tail anything.

Going to the Plesk's log file browser
https://domain.com:8443/smb/log-file/browser/id/37
there are no errors, while there should be some (php error_log('test');)

When managing log files with
https://domain.com:8443/smb/log-file/list/id/37
the path is shown as logs/error_log, like the sudomains with proper working error_log files.

When opening
https://domain.com:8443/smb/log-file/view/id/37?filename=error_log
the expected errors are there(!), so they are written somewhere (else).

Questions:

1. Where are errors written to, where is the real used error_log file?
2. What causes this behavior?
3. Can I change/repair it to default?

Thanks a lot in advance!

Meanwhile I found the location:
/var/www/vhosts/system/subdomain.domain.com/logs/error_log
So question 1 is answered while 2 & 3 are still open.

The directory /var/www/vhosts/<domain>/logs is a hardlink to /var/www/vhosts/system/<domain>/logs
The hardlinks are only updated after the statistics run in the early morning hours, so a newly created subdomain will only have the Apache logs in /var/www/vhosts/<domain>/logs after the first statistics run.
