After installing some user cannot edit the diagrams, but they can create.

What browser is being used by users that can't edit?

I can create but can't view or edit in

a) Firefox 45.6.0 and

b) IE 11 (latest)

I have the same problem, although no users can edit.

We've used for a while and created many diagrams which could previously be edited from the thumbnail. The thumbnails no longer show, and cannot be edited.

We have JIRA 7.1.7 and

(Same on Chrome, Safari, etc)

Was this resolved for you?


We're having the same issue, some users can edit and others can't, on Firefox. 

Check you attachment permissions in Settings.

Option "Allow Attachments" needs to be on.

Presumably JIRA Settings > Permissions (or project administration).

In the relevant permission scheme there is a section "Attachments Permissions".

All the appropriate user groups are enabled here to create attachments. I have even explicitly granted my username with no difference.


In the thumbnail position under diagrams on the issue, it sometime shows the error message "undefined: MXutiils.getAll is not a function" 


Please try clearing the plugin cache.
- Stop JIRA
- Delete these folders:
- Start JIRA

Did all that, no improvement.

Attachments are on; I apply attachments to many issues with no problems. The atatched files are still present on the issues, and can be downloaded ok. But no editing can be done and thumbnails missing. 

Cleared cache = same.

Uninstalled, rolled back to the previous version = same.

Uninstalled then re-installed latest version = same.

MXutils is a java component of MXdraw, which is from the same provider as I think. So presumably it's bundled with

I've reported to yesterday but no help yet.


I have found the problem.
Thought it best to check other add-ons for conflict. Rather than going into Safe Mode and reenabling one by one, i chose to disable one by one instead. Thankfully it was only the 2nd add-on I disabled and works again.
There was an add-on called "Database Schema Visualizer" which apparently conflicted so I have uninstalled it. A screenshot is attached for your info.
Screen Shot 2017-01-13 at 15.37.18.png uses a component called mxUtils which was presumably impacted by this 3rd party add-on.
Others with similar issue may find that installed add-ons may be conflicting so should check.
