I logged back into the libranet.de #Friendica account. "As I said before":{https://libranet.de/display/0b6b25a8-2064-0d61-7222-e4a224864189}, I'm not really using it because it is broken.

I don't know whether that is specific to that instance (or even the chosen theme ... I need to try another), but as my landlord's son used to say (when I was in high school): eess bloka (it's broken).
