Within a given project in my space, I go to the project settings page and there to issue types and select one of them (Epic, Tasks). When I try to put some custom field or a new field in a task, or simply when I want to delete a field in the task it does not let me and I get the following message:
"Could not save your changes.
There was a problem that prevented you from modifying the "Task" issue type.
Can anyone help me to solve the problem?
It turns out that if I delete an issue (for example "subtask"? and recreate it, it allows me to add new fields, but not the old tasks.
