I have used the “Make it flat” option quite a bit on 1.10 (1.11 too?), but it’s not working anymore on 1.12.
In hierarchical view the data table works just fine, but when I click the “Make it flat” option in the little cog at the bottom of the page, I get a “There is no data for this report” error.
This bug can be confirmed on the Piwik demo site:
- go to this page on demo.piwik.org
- go to the bottom of the page
- click the cog icon
- select “Make it flat”
Apart from this discussion on the forum, there is very little info on this bug.
I don’t have the permissions on the server or wherewithal to try the fix from this discussion, so any help or a bugfix release would be very much appreciated.
