Hi,
I have no upload rights on my seafileserver v9.0.2.
If I try to upload a file I got a networkerror output in the upload window.
Also if I try to change my Avatar it notify ma that changes are saved but I see a missing image.
I have no idea where I have to start to investigate where the problem sourced.
With this tutorial I saved my seafiel data also on a external harddisk: Seafile Daten auf externe Festplatte speichern - StephansNet
EDIT: It seems that the problem was solved. i have no idea what I have done to get it to work 
.
Cheers
