I have upgraded my JIRA 6.1.7 to 7.2.8. After successfull upgrade I'm unable to view "issue statistics gadget" on one of my Dashboards. But at the same time I can see other gadgets which are there in the previous version of that Dashboard.
In JIRA 6.1.7 I have
Pie chart Gadget,
JIRA Issues Calendar Gadget,
Issue Statistics Gadget.
In JIRA 7.2.8, I can see only
Pie chart Gadget,
JIRA Issues Calendar Gadget.
