When I want to go into the configuration of certain, but not all, of my configured Kanban Boards, the configuration page is not being loaded.
I re-indexed, Re-started, I increased allocated memory settings from min 384M to min 768M and max from 768M to 2048M and restarted again. No solution.
My Jira software is running at version 7.3.5.
Anyone had the same issue already? Any solutions?
See below screenshots. Thank you for your reactions!
