I've made the upgrade described as summary, and here is the result : - no more widgets on the home page, - when trying to change active period from day to week, I'm redirected to the current day. - In other sections, previous data seems to be lost, and no graphs shows up : 'Displaying Graphs in Piwik requires Flash >= 9.0.0' ; BUT i installed a fresh version elsewhere where i can view the graphs.
I'll try to figure out what went wrong, but if someone have any clues... Keywords: update, upgrade
Website URL? Do you have the fix from ?
Try uninstalling Flash completely. Run a registry cleaner. And then reinstall the latest version of Flash.
Also, clear/delete/disable the browser cache and restart the browser.
As a last resort, TRUNCATE TABLE piwik_user_dashboard;
Closing, as forums are more appropriate for further discussion.
