Spanish language option breaks navigation

[pablospanish9]

When I clicked on the Spanish option, your website translated it OK for that page. When I tried to navigate back to the English, the Spanish option was automatically tagged to your webpage and most navigation was broken. I could not freely navigate without this Spanish designation, which I did not want anymore, and most pages were not found.

Thank you for reporting, @pablospanish9. Quick question, if you for example go to https://developer.mozilla.org/en-US/docs/Web/JavaScript, then click on "Change language" and choose Español. The page will reload as es. Now, if you navigate around all is generally good i.e. it keeps the es locale?

If you now click on "Change language" again and choose "English US" the page reloads with en-US and navigating around keeps you in en-US?

When I tried to navigate back to the English

Did you use the "View in English" link?

[pablospanish9]

Yes. It keeps the es language and it seems to be working OK with all other pages. It stays in es. And I can click the English and it stays in English. I emailed the link to the one page where I received the error. It is possible that the behavior is limited to that one page.

It is possible that the behavior is limited to that one page.

Highly unlikely as they all use the same code logic. I think it may be that, that page really does not exist for es still. The es locale became a top-level locale in the last couple of days and so I suspect this will be resolved soon. If you want to bring this issue to their attention, please have a look at https://github.com/mdn/translated-content/

From you last description it sounds like things work as intended so, I am going to go ahead and close this issue for now. Thank you again for reporting and providing feedback.
