I think it’s very unclear what this error message wants me to do.
It happens for example if I try to comment on a post from kbin.social when I’m logged in to lemmy.world.
Where in “lemmy” am I supposed to update my settings?
I’ve set any language setting I can on my kbin.social profile, lemmy.world profile, and in the Voyager app.
You’re most likely getting the error due to a Lemmy bug, but just to be thorough, here is how to check the setting it is prompting you to set.
Optional: Unrelated to this issue, but while you’re there, you may also want to check that the Languages field:
If your Interface Language was already set, the issue you have replying to comments can be related to the language of the parent comment or post.
I’ve found Kbin comments are showing as Undetermined language on Lemmy, despite having a language set on Kbin. This can also occur if a user doesn’t have their Interface Language set and their browser cannot detect it.
When replying to an Undetermined language comment or post, Lemmy seems to try to use the same language and generates an error in the API/app. As @[email protected] mentioned in their comment, if you try to reply to a Undetermined comment/post in Lemmy via browser (not Voyager) it just shows a spinning loading button when you hit Post.
A work around is to reply to the comment directly on your Lemmy server via a web browser (not in Voyager), and select a language other than Undermined on the dropdown near the below the text field of your comment.
The parent comment/post issue is with Lemmy rather than Voyager, but Voyager are tracking the issue here.
