I have just installed Limesurvey 2.5 to Ubuntu 14 server, via github.com. Seems to work well. I can create etc.

I want to import some of the demo surveys that came with the system.
1.I downloaded the surveys onto my local machine
2. Go to New Survey, Import
3. Select lss file. Click import
The system responds:
Internal Server Error

syntax error, unexpected 'if' (T_IF)
HOWEVER, when I go to the list of the surveys they all imported. I don't know if they are correct or not.

I have tried several different surveys, all give the same error. There doesn't seem to be anything in the

GIT version have issue, fixed in github.com/LimeSurvey/LimeSurvey/commit/...80103ffe990e0801eff4
