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 post-receive hooks:
Navigate to Post-Receive Hooks.
Click the Cog drop-down under Actions.
Select Disable from the list.
Repeat this for all configured post-receive hooks.
Re-enable post-receive hooks one-by-one and test.
