Hey,

Ich bin's, $sitename.
|

Die Friendica-Entwickler haben gerade Update $update freigegeben,
|
||||
aber als ich es installieren wollte, ist irgendetwas schief gegangen.
|
||||
Das sollte schnell repariert werden und alleine schaffe ich es nicht.
|
||||
Wende dich bitte an einen Friendica-Entwickler, wenn du mir nicht selbst helfen kannst.

Meine Datenbank könnte ziemlich durcheinander sein.

Die Fehlermeldung ist '$error'.

Hey,

I'm $sitename.

The friendica developers released update $update recently,

but when I tried to install it, something went terribly wrong.

This needs to be fixed soon and I can't do it alone. Please contact a

friendica developer if you can not help me on your own. My database might be invalid.

The error message is '$error'.
