Tvheadend

Hi,
i am using TV Headend together with OpenElec 2.99.1
Until Yesterday a could add new Channels, but now i get an error
"Server Error unable to create new record"
Does anybody know this ?
Can i activate some debugging to see what happens ?

This is a line from the debug window:
There seems to be a problem with the live update feed from Tvheadend. Trying to reconnect...
Reconnected to Tvheadend
