When I go through the steps to change the "Story" to a "Sub-Task" it gives me this error when I click in the "Select Parent Issue" field (just when I click in it, I don't even get a chance to enter anything)-
"The Jira server was contacted but has returned an error response. We are unsure of the result of this operation."
It has been doing this for over a week. Is there a bug or am I doing something wrong?
