Error when trying to edit contributor: "Failed Ajax request or invalid JSON returned" [OJS]

Dear community,

today we upgraded from OJS to Most things work right away.
But after some testing I noticed the following error: I can’t edit a contributor in the List of Contributors (Submission -> Publication -> Contributors). After clicking the Edit button the error message “Failed Ajax request or invalid JSON returned” appears.

I have looked at the error.log, here the following error message appears:

[14-Jul-2020 13:02:29 Europe/Berlin] PHP Fatal error: Uncaught Error: Call to undefined function bindtextdomain() in /home/suburban/public_html/sys/lib/pkp/lib/vendor/sokil/php-isocodes/src/AbstractDatabase.php:87

What could be the cause of this error?

Thank you for your help.

All the best,

Hi @adm_sub,

Hi @asmecher,

thank you very much! I have installed the PHP extension gettext. Now I can edit the contributors in the list of contributors menu.

Warm regards,
