Upgraded Jira from 3.1 to 4.1, cannot see data for story points at JIRA Agile's issues. Configurations are ok.
The links-hierarchy-reports-1.1.jar does not work in conjunction with JIRA Agile 5.2.1 or higher.
The solution is to use links-hierarchy-reports-1.0-beta3.jar for solving this issue. Check the status of GHS-139 for a status update on integration of the Links Hierarchy functionality into JIRA Agile.
