after the Update to the new 2.12 Version, I got the message in the piwik-Dashboard that there would be no tracking data and that I should integrate the java-snippet into my footer-section. But the WP-Plugin works fine and the code is still integrated. I look around, but I cannot find any essential differences.
The only thing is, that in the WP-Plugin (WP-Piwik) the URL of the “REST-API” is set to my concrete subfolder b[/b] but in the administration section of Piwik it is set without my subfolder.
If I look to my realtime html source-code with my browser I could find the piwik entries, too.
I am sorry, you are right. I was a littlebit confused about that message.
My mistake was it to visit my own site with my Firefox-Browser and the acivated “do-not-follow”-option. I use the “Ghostery-Plugin,” too, but I set Piwik to a green status. The new visit with a normal IE was registrated correctly.
Thank you and now I have to learn more about piwik and it´s background.
