I’m working with OJS 3.5 and I’m getting a 401 Unauthorized error when the frontend tries to load the UI translation file from this path:

/index.php/[context]/api/v1/_i18n/ui.js


This is breaking the public site interface because the browser refuses to load the file due to the wrong MIME type and missing authorization:

lua


Refused to execute script ... MIME type ('application/json') is not executable ... 401 Unauthorized

I’ve confirmed that:

  • Apache is configured to allow access to this route
  • The request still gets blocked by OJS and returns a JSON error saying the user is not authorized.

Has anyone else experienced this?

I think you should download OJS 3.5 from official website https://pkp.sfu.ca/software/ojs/download/
Do not download from github

Hi, I have exactly the same problem. I downloaded the installer from the page indicated.

Failed to load resource: the server responded with a status of 401 (Unauthorized) ui.js:1

Thank you for the recommendation.
I confirm that I downloaded OJS 3.5 from the official PKP website:
https://pkp.sfu.ca/software/ojs/download/
I did not use the GitHub version.

Hi all,

See For anonymous OJS users: ui.js (which generates locale strings) is not available if allowed_hosts is not set · pkp/pkp-lib · Discussion #10491 · GitHub – I suspect you have not set the allowed hosts setting in your configuration file.

See config.TEMPLATE.inc.php for an example, and review the release notes for further information.
