@jan luca You should have realised by now that this forum is in English, haven’t you? So please make sure your post is written in a way that all users can read it.
I’ve already told you in one of your posts how to do it. The forum is also displayed in German for me because of the browser’s online translator. Before you write a post or reply, you need to uncheck the box for ‘Translate to German’ in the browser’s online translator, then refresh the forum by pressing F5 so that everything appears in English. Then write your post or reply in English, and afterwards you can switch the browser translator back to ‘Translate to German’. I have to do the same when I want to write something here.
