"Report definition is obsolete" when opening reports
When opening reports in the RIO Education folders, you may find that some of the reports have no data to display. Instead, the attached error message may be displayed:
We couldn't complete your request. The report definition is obsolete. Your administrator has disabled all reports for the custom object, or its relationships have changed.
You may want to check the status for "Allow Reports" in Optional Features.
To prevent the issue stated above, make sure these objects used in those reports have this feature checked.
