Hi,
Make sure that the user running Apache (apache, httpd, nobody) is able to write to the log directory /var/log/httpd. If you are using cronolog v1.7.0beta or v1.6.2 with the jumbo patch added you can specify the use that will own the cronolog process and the log files.
Code:
CustomLog "|/usr/bin/cronolog -u <logowner> -p '12 hours' /var/logs/https/access%Y%m%d%H" combined
