Hi @IJBSRR_Journal,

Is this occurring when you attempt to configure the ORCID plugin? Have you checked your PHP error logs for any relevant details that point to what the error is?

Yes, When i attempt to configure the ORCID Plugin then show above screen

Thanks for verifying. Having PHP error log messages would be helpful, as the “Failed AJAX request…” message isn’t very helpful in indicating what the issue is.
