Platform problem

Good night!
We are having a problem with the OJS platform Current Version: When I access the platform to proceed with the evaluation and publishing activities, I noticed that the system has an error that does not allow downloading the files, it has the following error: {“status”:false,“content”:“O papel atual n\u00e3o possui permiss\u00e3o para realizar esta opera\u00e7\u00e3o.”,“elementId”:“0”,“events”:null}
This happens when I download a file that was attached.
Could you help me.
Kind regards,
