Exception is only reproduced on Roll-Up view.
"A fatal error occurred
The following error just broke Piwik (v3.2.0):
Key "1" does not exist as the array is empty.
.../plugins/Live/templates/_profileSummary.twig line 24"
Did you maybe remove a goal after some conversions were tracked?
No, we did not change a goal. I just checked: the goals did not change more than a week, but the visitor was registered today.
Does the error always occur?
Yes, the error appears every time. Restarting a web server and disabling plugins does not help.
@efedorov I'm not sure how this problem occurs. Could you check if applying following changes fixes the problem for you: https://github.com/piwik/piwik/compare/fixgoalvp#diff-e968bd8d9abc8cf8161a4c09567ddc52
