I started to use Piwik (after many years mit phpMyVisits) with version 0.2.33 and started with only me as (super)user and 2 websites.
Now I updated (manually, as there was no update alert shown on my dashboard) to version 0.2.37 and all statstics displayed fine. But when I tried to add another website and another user, in both cases I get this “Loading data…” which stays forever and nothing is added.
What am I doing wrong?
