New visitors not processed

Good afternoon,

Since 3 days I use Piwik and this is my second installation.
I notice that when there are new visitors or those in the visitor log to be kept, but there is nothing else done with the data.
Is this a known issue and has something to do?
I hope so because what I’ve seen this is a great software package.

Best regards,
Lars

Sorry, maybe to fast, but no one?

Greet, Lars
