Error when uploading paper (editing module)

Hi

After reviewing finished, authors are required to upload final PDF through editing module. Many of them were able to do so, but today one of them obtained the following error:

Note that I replaced some URLs with XXX and the name/email of the user.

The error sems to be “The contributions of this event have not been published yet”. I dont understand why some authors could upload the paper and this one is not able to do that

Thanks!
