I just discovered that my Apache 2.2.8 just logs in his access_log the string plesklog since a few weeks. Normally it looks like that - - [19/Jul/2013:04:37:32 +0600] "GET /infos.html HTTP/1.1" 200 12371 "" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:22.0) Gecko/20100101 Firefox/22.0"

Currently it looks like that:


My apache2.conf looks like that:

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %T %{mod_php_memory_usage}n" combined
LogFormat "%h %l %u %t \"%r\" %>s %b %T %{mod_php_memory_usage}n" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent

You need to look at the CustomLog directive. I suspect there is a faulty format given there. – kekkis Sep 30 '13 at 19:59

After the comment of kekkis I discovered that all my CustomLog [path]'s of my VirtualHosts had specified a LogFormat name plesklog so I added in my main apache configuration file the line:

LogFormat "%h %l %u %t \"%r\" %>s %b %T %{mod_php_memory_usage}n" plesklog

And now everything gets logged as it should.
