Hi, I can successfully synchronise my address book with my mobile phone. When I synchronise my calendar+todo, I get – after quite some time – the error 500 and 406. I appended a snippet of the log file. The messages with a non-OK status are at the end. What is the best way of debugging this? Can I find out what element makes problems? (Maybe I can simply delete it.) Thank you very much for your help, Simon [2010-09-23 18:13:48.026] 'SyncML_Outgoing' - preparing for response before starting to analyze new incoming message [--][++] [->end] □ + – [2010-09-23 18:13:48.026] 'SyncML_Incoming' -
