The fix works (at least for me). This is what I have done:
Auto update to 0.6.4 fails. Read a lot of posts here at the piwik forum.
Manual update, like described [here[/url].
/piwik/tmp/assets set to 755, files inside deleted
Download AssetManager.php from [url=dev.piwik.org/trac/ticket/1497]dev.piwik.org/trac/ticket/1497](piwik.org/docs/update/#toc-second-option-the-manual-three-step-update) and FTPed to /piwik/core/
Logged in to my Piwik. Everything works.
I would like to thank you, Matthieu, for doing an awesome good job.
Thanks for the replay. Now I have deleted the described files once more. But I still get the same error: The Dashboard does not get loaded; the console shows the same error…
I have downloaded AssetManager.php and overwrite it but nothing happens.
I deleted tmp/* content but nothing happens
My dashboard is empty and without any widget. It is strange because I can to other menus (Visitor, Actions, Referrers, Goals, etc.) and I see those widgets. My question is, has dashboard same code that these menus/sections???
I just want to add that I have the exact same problem.
Tried the new AssetManager.php and deleted /tmp/assets/* to no avail.
I noticed that if I create a new user with admin rights and log in as that user, all is OK and dashboard widgets display.
If I log back in as the superuser dashboard is broken and no new widgets can be added.
I discovered that creating a new admin user and logging in as this user gives me a dashboard with correct functionality.
Only the original admin superuser is broken.
