Unable to delete the incompleted submissions

i submitted some metadata and files trying to figure out how ojs works but now when i am trying to delete those files, i am getting this error. what can be the cause of the error… ##api.submissions.unknownError##

Hi @dwangdi

You are using the latest OJS 3.1.1-2 version, right?

How do you try to delete those submissions?


yes i am using the latest ojs , i went to archives and tried to delete using the delete button.
