Hi,

Version JIRA uses: 7.4

Please see screenshot.

I've seen this happen when an add-on that uses some javascript does it badly (in my case, I'm really bad at javascript...)

Is it possible to temporarily enable "safe mode" (all add-ons off) and try it again?  If the problem goes away, then we know at least it's an add-on.

I have enabled the "Safe mode" but the issue is still the same.
