I’ve been a long time user of Piwik, running the same installation for years and updating over time. I upgraded to 2.10.0 and it seems to have broken the bounce rate reporting as you can see below. I think it’s just a display error, as old stats are doing the same thing. For example, what used to be 70% bounce rate is now showing as 0.70% on both the graph and the tooltip.
same problem here, but what’s more, conversion rate is also miscalculated the same way in the goals-graphs.
A conversion rate of 5% would show up as 0.05%.
