Dear all,
Yesterday I tried submitting to crossref for doi registration and I got this error:
Validation errors:
Element '{http://www.crossref.org/schema/4.3.6}journal_volume': This element is not expected. Expected is one of ( {http://www.crossref.org/schema/4.3.6}contributors, {http://www.crossref.org/schema/4.3.6}publication_date ).
Could not convert selected objects.
My xml output is here:
https://pastebin.com/ZVjiyXsJ
Then I deleted the following lines and submitted manually from crossref webiste (successfully):
<journal_issue>
<journal_volume>
<volume>5</volume>
</journal_volume>
<issue>2</issue>
</journal_issue>
Last time I successfully submitted from OJS interface was on July 22, 2017 before upgrading to OJS 3.1.
I would like to know if I have some problem in my system or is there some problem with OJS configuration of crossref requirement. And, how to solve it.
Regards,
