Hi watcher
Ok, looks as if we discover a new bug here
First message didnt make any sense to me (headers already sent) but in combination with the second (undefined index) a little more.
Could it be that the regions have an owner UUID that was deleted somehow? This would be the only explanation to me.
Of course, jOpenSim should catch this somehow and return "unknown" or similar rather than throwing a PHP notice and I'll try to fix this also soon.
