Thank you for the debug line to add to the config.php. At the bottom of the page it says, "error" on page then it goes away and says, "Done." But nothing happens. It just won't save the survey.
The problem is in my Windows. I tried setting up the survey on a different computer, and it worked fine. I need to reload my computer from a clean install and get the bugs worked out on that end.
Also, I had a different version of limesurvey last year and had no problems creating the surveys I wanted. I've since added Office 2007, and some of the problem might be in the Office.
