After upgrade from 1.6 to 1.7.1 a lot of my dashboard widgets (all default ones) try to load data without success (message: Loading widget, please wait… does not disapear) and I got the error message:
Oops… problem during the request, please try again.
I can add new widgets other than the default ones and they work (exept ‘Graph returing visits’) but Piwik does not save them in the dash and they are gone after sign out. “Reset dashboard” does not help either.
The other widgets outside the dashboard work as expected. In “Widgets” (Link in the header) the widgets which do not work in the dash work here (exept ‘Graph returing visits’). Weird.
I did all the actions written in faq entry 148 “After I updated Piwik, it stopped working (blank page, widgets not loading, error message, etc.).” but I have not had success. I deleted all files and reinstalled Piwik from a new and fresh download from scratch (but I reused the old database). That did not help either.
Any ideas from the experts? Thanks in advance.
