XML Crossref files miss the title´s prefix

Hi everybody!

(Using OJS version)

I have recently noticed that XML files generated by CrossRef plugin are missing the information regarding the prefix of the title. This is a problem that was not happening before. Does anybody else observe this?

I thought maybe the plugin needs an upgrading, but I don´t see the option to do thta when cheking the Plugin gallery or the plugin options.

I have cheked the forum and haven´t seen any topic about this issue.

I´m attaching two pictures from same DOI to contrast the info that the DOI currently shows and the info that shows the XML file that I generated today.



Thank you very much for your help,


Hi everybody,

My problem persists. Trying to find out something I found that the problem started when we upload from 3.2.0-3 to

Does anybody else using 3.3 find this problem?



¿¿ El XML que muestras es el DOI o el generado por al OAI ??
Aquí hay otros post que le ha sucedido algo similar

I had the same problem and made a Pullrequest which is now merged into the code.

You can apply the fix manually if you can’t wait for the next release.

Hola Dago,

No, el OAI lo muestra bien, así como los XML de exportación. El problema está en el plugin de CrossRef. Vamos a probar con la solución a la que han llegado Edelm y Asmecher.


Thank you!! It worked!
