Hi i was trying to post a comment in a thread on Lemmy.world but everytime it wouldn't post and a toast popup that said "Language not allowed". My comment didnt have any course language in it at all. I reworded it and tried again but still the same thing..
I don't think “Language not allowed” is related to your wording, but to the actual language the post was written.
Was the thread in English or some other language?
Below the text box, on the right where the icons are, there's a drop down menu in which you can select the language of the post, that thread probably wants you to select a language that matches the one set in the thread.
