Kontact can't write to kolab?

[Nick Wiltshire]

Hi All,

I'm using Kontact 4.14.3, and every time I try to create an event or todo on 
my Kolab server I get "An error occurred while writing the item to the 
backend".

It works from my phone and roundcube.

How can I get more info on *why* it can't write to the backend?
