I have an issue with language translations. I have defined ‘es-es’ as the LANGUAGE_CODE in tutor’s config.yml file, but the translations on Django’s settings do not affect to the themes (see screenshot below). I am currently working on updating a tutor 16.1.5 instance to tutor 18.2.2, I have to say that this configuration worked perfectly in version 16.1.5.
Then I needed to change my MFE to integrate the new ATLAS language processes, so I needed to fork openedx-language to add some custom strings and setup ATLAS_REVISION and ATLAS_REPOSITORY (if you don’t have customized strings I believe you won’t need this change)
Hope this help you to find the solution to your issue
