My Piwik which is self-hosted on my website using the latest version of Wordpress 4.2.2. Piwik stopped recording suddenly on 11th May 2015. I can still access the Dashboard and Visitor Log but the recording of visitor activities has stopped.
I updated my Piwik to the latest version 2.13.1 on 9th May 2015.
Does anyone else have the same problem?
