Tempo Holiday Scheme Screen Crashes

[Ranganathan]

Hi, 

We recently uppgraded to JIRA 6.4.12 and initially the Tempo Holiday Scheme screen was working. 

Recently when we tried to access the screen, it is getting crashed, same with the Workload scheme screen.

When we check the Logs, we found the following error:

2016-05-05 15:55:25,376 ajp-bio-172.00.000.000-8009-exec-804 ERROR XXXXX 955x2263974x1 j82l88 172.00.00.000 /secure/TempoHolidayScheme!default.jspa [velocity] Exception rendering #parse(com/tempoplugin/core/admin/help.vm) at com.tempoplugin.tempo-core:tempo-holiday-scheme-ww//com/tempoplugin/core/holiday/holidayScheme.vm[line 14, column 13]

Could not found any resolution when googled.

What does "getting crashed" mean? Perhaps there's an error on-screen, an HTTP 500 error, or it freezes up?

Have you tried disabling and reenabling the add-on? Perhaps reinstalling the add-on? Maybe stopping and starting your JIRA?
