I ran a Google Pagespeed test on my instance and received the following message:

 ![Screenshot 2026-05-09 at 6:24:38 AM](https://global.discourse-cdn.com/meta/original/4X/a/0/9/a09ed6bc343c3d11a9d71d737c0c61a518fbf8ac.png)

I can’t explain what’s causing it. Is there an error in the translator?

I think the invalid code comes from Discourse.

Maybe instead of `hreflang="<%= locale %>"` it should be `hreflang="<%= locale.tr('_', '-') %>"` to replace the underscore.

I have submitted a Pull Request to fix this in the Discourse repository:

[https://github.com/discourse/discourse/pull/39884](https://github.com/discourse/discourse/pull/39884)

This change ensures the `hreflang` attribute is SEO-compliant while keeping the internal locale parameters functional.

Thank you for your PR, I’ve added specs and merged it.
