Modlogan only analyses the first two days of my monthly logfiles

Hi,

I'm having a problem with ModLogan analysing my monthly logfile. In the 
output html file, there is only the data for about one or two days. The 
other days seem to be forgotten?

My config file is below. I'm sure the mentioned directories exist.
Modlogan reports no problems. It says to parse e.g. 1158 records, and 
the number of lines in that log file is 816.
The report only shows the first one or two days.

The reports are in .gz format.

I used to work with Webalizer, which could handle the .gz files without 
any problem.

I don't know where to look for the problem...
Thanks for any ideas...
Thomas


My configuration file:

[global]
# replace ${prefix} with the compiled prefix (e.g. /usr/local/)
includepath    = /usr/local/etc/modlogan
include        = modlogan.def.conf,global

loadplugin    = input_clf
loadplugin    = processor_web
loadplugin    = output_modlogan

## can be the same as the outputdir of the output-plugin
statedir    = *************


incremental    = 1
debug_level    = 3
#enable_resolver = 1

#read_ahead_limit    = 100

## configure the processor
[processor_web]
# to group known bot attacks like Nimda and CodeRed
include        = group.url.conf,group_exploits
# to use the german file extension descriptions uncomment the following
#include        = group.extension.conf,groupext_german
# include the default config
include        = modlogan.def.conf,processor_web


debug_searchengines = 1
hidereferrer    = "^http://www\.**********\.com"

# if you are running multiple virtual hosts
#splitby    = srvhost,"(.*)",$1


## configure the output generator

## configure the parser
