Hey riq, just a quick update about this behavior.
I just posted a score ingame, and scorePostFail was called with status=kPostStatusPostFailed
Incidentally, the score was actually posted and appears on the server, but it screwed up the rankings (all the scores below it weren't shifted down one rank), also the debugger logged this message:
wait_fences: failed to receive reply: 10004003
hope that helps you debug the problem,
thanks
patrick
edit: Also, would it be possible to display the ranking for a score in the edit scores section of cocoslive? This would allow me to understand which score is causing the ranking problem and delete it manually, until this issue is fixed.
double-edit: Well, if I show both "edit scores" and "view scores" for the game, I can figure out the ranking for the scores, and pinpoint the problematic score and delete, I've tried it and it works.
