Unfortunately, the cloud server has completely crashed, and restoring the existing backups did not help either.
I have now moved the website to a normal web space and will try to get the whole thing up and running again tomorrow.
At the moment, there will probably be problems with the redirects – this mainly concerns the direct install on Android.
This will also be taken care of tomorrow in the course of the day.
Sorry for the trouble.
PS: The registrations and forum posts of the last 24h are unfortunately also lost, sorry.
