Update 2.5.0 and no logging at all

Thanks, unmus_blog.
It is the cronjob. I’ve changed back the setting to YES


Settings > General Settings > Allow Piwik archiving to trigger when reports are viewed from the browser: [b]YES[/b]
and the browser shows (after a while) the tracking information.

Now I need a hint how to get the web cron working again.

When you are using a webcron, can you try visit the webcron URL directly, what output do you see there?

Hi matt!
The page is empty, no output in browser, if I enter the webcron URL.

and do you see an error in your server error log?

Also could you delete any section [log] that may be present in your config/config.ini.php ?

Sorry for the stupid question, in which file of piwik I have to look?

I receive a blank page only too, when I access the webcron url directly with the browser.

@matt
Do you refer to the server logs or piwik logs?

FYI
Now it works after update to v2.6.1 (including web cronjob).
