Calbre Companion: No items to display
I've enjoyed working with Calibre Companion on my adroid tablet.
I could connect to my PC and see all the books.
But suddenly, when I connect to my PC, I get a blank screen and it says: "no items to display"
The connection to the server is ok. (I'm asked to login, as I configured in Calibre-preferences)
There are books in the catalog. I see them when I open Calibre on my PC.
When Calibre is not started on my PC, I use the bachcommand "calibre-server --auto-reload --url-prefix /calibre"
Any ideas? Why are all my books gone ?
