After upgrade to Debian 8 and Apache 2.4 the vhost configuration file has not included lines regarding apache access log. And all logs a writes to common other_vhosts_access.log file under Apache log folder. ISPConfig Version: 3.0.5.4p8. How should I make to write access log to site specific log instead of other_vhosts_access.log?
The access.log had never a directive in the website vhosts in ispconfig 3 as the log definition is set globally. To fix your problem, download the ispconfig 3 tar.gz file, unpack it and run the update.php script in the install folder. choose to reconfigure services during update.
