If you are having issues with a specific feature of ScriptRunner, we suggest disabling all ScriptRunner scripts for that feature and re-enabling one-by-one to identify the source of the problem. For example, to troubleshoot jobs:
Navigate to Jobs.
Click the Cog drop-down under Actions.
Select Disable from the list.
Repeat this for all configured jobs.
Re-enable jobs one-by-one and test.
