On April 10, 2013, we upgraded Limesurvey to the latest version.
This appears to have solved a number of outstanding issues including not being able to generate graphs for reports, not being able to save surveys in progress, and not being able to generate PDF versions of results. These issues have now been fixed.
I'm sure you will notice that the upgrade had changed the look and feel of the system. The main functionality has not changed much and all of the buttons are in the same place they used to be, although the button pictures have changed. This should not affect your ability to use the software.
All your survey data should be in the upgraded system.
I will try to update the training docs for Limesurvey to be consistent with the new look and feel, but I don't know how soon I'll be able to do this.
One thing I've noticed that isn't working in the upgraded version is the RCH branded survey template. I will fix this as soon as I can. In the mean time, please feel free to use one of the standard templates that come with Limesurvey.
