Hi,
We use OJS 3.2.1.1 and we have the following problem with assigning the DOI to an already published article.
When I am going to assign it I have the following message:
You can not generate a DOI until this publication has been assigned to an issue.
The publication is already assigned to a number.
If I try to unpublish the number to try unpublish an publish, and I’m going to assign the number, it shows the following message:
A DOI has not been assigned to this publication.
if I’m going to assign the DOI it shows the message:
** You can not generate a DOI until this publication has been assigned to an issue. **
Do you have any ideas what I can do to assign the DOI?
Thanks,
Andrés
