Error when deposit and export new DOI of articles

Reza_Mahdi · March 19, 2024, 10:18pm

Hi everyone,

I have upgraded step by step the OJS version from 3.2.1.4 to the latest version 3.4.0.5. Now I am using PHP 8.1 and all table types in the database are InnoDB. Now, I have problems when depositing DOI and generating DOI XML file via export DOI.

If I click the Deposit DOIs on the Bulk Action button an error will appear but the article status changes to Submitted as shown in the image below, but the DOI doesn’t work. And I can’t edit or delete the DOI in that article.

Then, if I click Export DOIs to create a DOI XML file for that articles or new articles, but the same error would appear.

This is my journal link https://megasains.gawbkt.id/

This is the error picture

and this is the PHP error log file

Hi,

Same problem here.
Did you manage to resolve it somehow?

Regards.

Hi! did you both see this post too? CrossRef XML Export Plugin errors after upgrade to PHP 8.0.30
Sounds like maybe a similar issue?
You can also double check your cross ref credentials in the plugin settings.

Reza_Mahdi · March 21, 2024, 11:15am

Hi Ehopkins,

Thank you for the informations. I’ve never seen that post before.

Previously, I had checked ref credentials in the plugin settings and everything was correct, including my Crossef username and password.

We hope that there will be the best solution to this issue as soon as possible…

Hi!

Your server should be able to access this URL:
https://www.crossref.org/schemas/crossref5.3.1.xsd

If it doesn’t, then this error will happen, I think it can also happen in limited environments where the server blocks certain PHP functions.

Best,
Jonas Raoni
