DOI registration error

We have tried to register the journal for DOI but faced with the following error:

Element ‘{}journal_volume’: This element is not expected. Expected is one of ( {}contributors, {}publication_date ).

Would you please advise what we need to do.

Thank you and best regards,


Hi @rbabaei30,

Please tell a bit more:

  • which OJS version are you using
  • where did you get that error, in OJS or on the CrossRef
  • can you please attach the XML file for the CrossRef deposit

Regards, Primož

We just joined Crossref and dedicated a DOI to our articles.
We get such an error when we click on the DOI code of articles.
Please help me.
