Hi again, @roadscape: I think it's really interesting that as soon as I copy the original source from your link: (https://steemd.com/deutsch/@jaki01/bundesregierung-fuer-pflicht-zur-passwortherausgabe) into the Steemit editor the preview is absolutely correct again! Then I can edit my post. However, when I click at "Edit" under my post, the editor shows a completely different source code!
