Ok, my bad, i’ve done strange changes to my config.ini.php.

This error was due to theses lines in my config.ini.php:

[PluginsInstalled]
PluginsInstalled[] = Login
PluginsInstalled[] = AdminHome
PluginsInstalled[] = UsersManager
PluginsInstalled[] = SitesManager
PluginsInstalled[] = Installation
PluginsInstalled[] = PluginsAdmin
PluginsInstalled[] = API
PluginsInstalled[] = Widgetize
PluginsInstalled[] = Home
PluginsInstalled[] = Actions
PluginsInstalled[] = Dashboard
PluginsInstalled[] = Referers
PluginsInstalled[] = UserSettings
PluginsInstalled[] = UserCountry
PluginsInstalled[] = VisitsSummary
PluginsInstalled[] = VisitFrequency
PluginsInstalled[] = VisitTime
PluginsInstalled[] = VisitorInterest
PluginsInstalled[] = ExamplePlugin
PluginsInstalled[] = Provider
PluginsInstalled[] = CorePluginsAdmin
PluginsInstalled[] = CoreAdminHome
PluginsInstalled[] = CoreHome
PluginsInstalled[] = LanguagesManager
PluginsInstalled[] = ExampleAPI
PluginsInstalled[] = ExampleRssWidget
PluginsInstalled[] = ExampleFeedburner
PluginsInstalled[] = Feedback
PluginsInstalled[] = CoreUpdater

[Plugins_LogStats]
Plugins_LogStats[] = Provider

[Plugins_Tracker]
Plugins_Tracker[] = Provider

So i guess this bug should be transformed in “make piwik give verbose errors on faulty config files.”

Are you running Piwik on a Windows-based web server?

No, i’m running it on Debian GNU/Linux 4.0 Etch , and i use Lighttpd as server. PHP5 is run in fcgi.

Hope this help.

I’ve played with my configuration file config.ini.php to get the two lines that are change in default.ini.php in the auto archiving tutorial to be changed in config.ini.php. It was the source of the problem.

this is actually the same as bug #26
this should be easy to fix and is to be fixed in this roadmap (next 2 months)

the problem happens in [core/Config.php](https://github.com/piwik/piwik/blob/master/core/Config.php) ; the implementation is faulty. Instead of reading both config files and merging sections, it should simply merge both files and read it once with zend_config. We should fix it.
