Gantt Chart Not Displaying

Question

I'm troubleshooting an issue with JIRA Gantt-Chart Project, and I can't quite figure out the problem.  Does anyone know how to resolve the below?  The short of it is this:

* For one user (me), the gantt chart appears fine.  (Screenshot attached.)
* For another (a fellow PM), the gantt chart doesn't appear at all when clicking on Resource Planning, Project Planning, Resource Tracking, and Project Portfolio Tracking.  In these cases, no error is displayed.  Instead, you get a near blank screen.  (Screenshot attached.)
* For Report Tracking, the error in the screenshot below is shown.  It is thrown a number of times.  After I click OK a scrillion times, it shows the proper chart.  (Screenshot attached.)

I chose to use Frank's plugin instead of the one mentioned in the question above.  This question is no longer relevant.
