I have been using Piwik for a while with no problems. I was getting some access issues on one site after the update to Matomo, so I have just been trying to sort this out. I am currently running 3.5.1 self hosted.
What I noticed was that previously I had to login to analytics with my username and password, but now it is wide open an on the public internet. To make things worse the url is in the tracking code, so basically anyone could easily look at the site analytics.
Any ideas what is happening and why I am seeing this. I can get to the site from browsers and devices that have previously not accessed the site, so it’s not a cache issue.
