Localization changes depending on whether you are logged in or not

[wildworks]

On wordpress.org's Japanese site, I noticed that the display of the pages under the support directory changes greatly depending on whether the user is logged in or not.

Using ​https://ja.wordpress.org/support/view/all-topics/ as an example, when a user is logged in, the following problem occurs.

• Much of the page is not translated
• Some links change to wordpress.org instead of ja.wordpress.org
• The updated date and time of the forum are displayed as "sometime ago" and the correct updated date and time are not displayed.

Hi @wildworks
Have you, by any chance, in your .org profile opted for English as your back-end language?

get_user_locale() is indeed en_US for both of us (and is for most users), although AFAIK that's not supposed to be respected at all on the front-end of rosetta sites; nor is it consistently applying if so.

Setting mine to de_DE and visiting ja.wordpress.org didn't result in German text though, it was untranslated still. I feel like this is likely a translation filter issue, as this text is translated via filter.

I accessed the support forum dashboard and checked the language of my profile, and it was English. When I changed this to Japanese, I confirmed that the Japanese site was displayed correctly, just like when I was not logged in.

However, even if the profile language is English, it is inconsistent, as it is a mix of Japanese and English, and some of the links do not refer to the ja subdomain.
