Even if I setup jira in the safe mode the exception is still present and it impacts only my profile. For others users it works fine.

Hi Basile,

Since this is only affecting you, I would do the following:

  1. Put your browswer in Safe Mode and try it again.  If this does not produce the same behavior you'll want to look at Browser add-ons.
  2. Try another browser.

Since it's only happening to you I am a bit hesitant to think it could be the proxy, however, from past experience it could be.  If you are using a proxy, follow the steps in How to bypass a Proxy and SSL to test network connectivity to bypass the proxy and test. 

* Be sure to use a port that you are not currently using.

Try those things and let me know the results.



Our tester has been testing the latest JIRA Software 7.4.1 and 7.4.2 as part of our upgrade from 6.4.x and has encountered the same error.


  • Unfortunately, we have yet to pinpoint the exact steps to simulate/reproduce but have seen the error on more than one occassion on IE11.

I do have a similar problem after upgrading jira.

7.6.0 and 7.6.1 show this behaviour, all agile boards crash:

Hi Christian,

The No jira/editor/customizer has a knowledge base article titled Exception: Error: undefined missing jira/editor/registry when accessing when any agile board:


The caused of it due to the Documents third-party plugin is not compatible with the JIRA version you are running.


Update the plugin to the latest compatible version.



I do not have this addon installed. But thanks anyway.

I narrowed it down to the Jira Service Desk addon. If I disable Service Desk, boards are working again. Problem is, we need Service desk.
