We just upgraded JIRA Agile to 6.3.8 from 6.1.something and noticing today that Kanban boards are slow to load. So I checked the Agile Configuration page in JIRA Admin and see the bottom field:
Worklog cache limit: 0
I had previously set this to 50,000 as we'd maxed out the previous default of 20,000. Now I cannot even change that number to 1, let alone 50,000.
Anyone else see this? Has this moved to a DB/file change required on this, or is there some secret "save" button (never was one before) that needs to be hit?
