I have detected that one of the published articles does not show the DOI url. I access the control panel, I access this published article and I access the section Metadata of sending and publication / Identifiers and I see that the url is assigned.
What can it be because it only happens in this article?
It has the DOI assigned because it appears in the identifiers section. Where the “Assign a DOI to this article” check box is selected. I await your response.
If I don’t want to assign DOI, what should be done? I uncheck “Assign the DOI to this article” and save but when I go back to the “identifiers” tab it is checked. Is it a plugin bug?
