Can you please have a look at my issue with the log rotation? -> https://forum.howtoforge.com/threads/error-log-rotation.90262/#post-451136 (Sorry for creating a new thread, but the other one is not in the priority support so I thought this is the right way to "escalate" it. Thanks)
You said you change done of the symlinks there, but did not reported back if that soved your issue. That's why there were no further answers posted in that thread.
