Date/time picker editor is corrupted

[Amir Katz (Outseer)]

Hi,

When I try to edit a date/time picker field, I get a corrupted calendar display (weekdays are not above the calendar).

See attachment below called CCB 10014. This happens on a Jira server 7.11.2

In an older server (6.4.11), it works as expected - see attachment called SOSP-3758

It happens to other people as well, so I'm pretty sure it's not a per-user issue.

I opened an incognito browser window, and it still happens, so I assume it's not a cached settings.

It happens in Chrome. I also checked it in Internet Explorer - same problem.

Anyone?

An official support ticket was submitted to Atlassian. With their help, the reason was identified to be an old version of an add-on - BlackDuck 4.1.7.

Once the add-on was updated to the latest version (4.2.1) the problem was fixed.

I'm not sure why your system is doing this.  I can't recreate this on my own yet.   However I am suspecting that you might have some kind of javascript or css modification in your announcement banner of Jira that might be causing this to happen. 

Even if you don't have anything there, it is possible that you might have a plugin in Jira that is causing this as well.  Some of them can run scripts that effect other elements like this.  But narrowing it down can be difficult.   You could try to disable plugin in your Jira instance, if you are a system admin, one by one in order to see when this problem disappears.   You could disable a plugin, then reload the page and test out the date picker to see if it loads as expected.   The major problem with this approach is that your other Jira users could be negatively affected by disabling plugins that they might rely upon.

It might be more advisable to try to troubleshoot this same issue in a staging instance of your Jira site with the same data/plugins.  That way your Jira end users would not be inconvenienced by the steps needed to troubleshoot a problem like this.
