First of all thank you for Piwik, its a great tool! My problem is I installed the piwik plugin in my blog and for some reason it just stopped working. As far as i could see it was all configured correctly so after a while I tried the "Reset WP-Piwik settings except auth token and Piwik URL option". After that my blog crashed and when it recovered I tried completely deleting and reinstalling the plugin which didn't work either. On the tracking configuration, when i select the option it just says "waiting for www. etc and it does nothing. I would appreciate any help you can give me because I'm really not an expert in this. thanks!
