Piwik is sending users multiple identical email reports. Regardless the interval (daily/weekly) 2 or 3 emails are sent for each report. I am using Piwik on a shared hosting server with GoDaddy running PHP5, and is configured under the Piwik admin login. It is happening for all the websites and all the users that are configured to receive emails. All copies are received within the same few minutes.
After researching to see if this is an isolated incident, I found this ticket which was recently closed.
