Hello, I just came here and was experimenting on the demo survey - then it died. I guess this is an issue, the main thing I was doing which was not standard was trying to add multilingual info. I was making my first question group when I got the below php error dump. After this all of the demo surveys disappeared from the list.
The demo system is reset daily, you were probably active at the time that happened. If you can do it again (not at the same time of day please to rul eout the possibility of system reset) please file a bug report.
