Users cannot create subtasks

Dale Fraser2

Since upgrading from 4.2.x to 4.4.3 users can't create sub tasks

They see the + when clicking this nothing happens. As an administrator it still works

I figured it must be a change with permissions or issue types etc but after attempting to resolve it and googled around had no luck.

I don't recall any changes like that between 4.2 and 4.4.

Do you see any traces of a problem in JIRA log file? (best check both atlassian-jira.log and catalina.out).

Also has your upgrade process finished without any errors?

Also it's advisible to fully refresh the web browser as it may still remember old resources (especially CSS and javascript files) for your old JIRA installation (if the new one runs on the same URL).
