We use JIRA 6.1.7 and after upgrading to 2.3.12 we started having an accessibility problem with most users: they could not edit Agile Cards settings on project level - for some a popup appeared with login box and a "lack of permissions" message, for others pop up with template edition was immediately dissapering after opening but a grayed-out area hovering whole page was staying still on top of screen (it was disappearing only after full page refresh).
We tested all 3 versions with FF 25 and 26 and this problem appears in all. We had to downgrade to 2.3.9 to get rid of the problem.
Can we count on a fix?
