Hello again,
I had some todo that was disappearing from my todo list.
I found some interesting informations in my browser's console :
"Error: 'https://user@server/dav/user/collection/f5a5c92f3c57cb650e3c946b7a4d46715480...': unable to parse vTodo"
How can I check the reason of this parsing error ?
The item has been created by infCloud.
The backend is still radicale.
Other items are working perfectly.
