Hi,
I have used lime survey several times years ago and have never had a serious issue.
I started a new survey few days ago. The survey was anonymous and set on 'public' so that anyone can answer clicking de link. All looked fine.
BUT soon I got some feedback pointing out a serious issue. Some respondents told me they had filled the survey (which is true bcd they knew what the last question was about) but I can't see their response on the tab. In some cases, the ID wasn't even created. Sometimes, when they agree to fill it again, results eventually show up, sometimes not.
For some others it is working fine though. I feel I am loosing dozens of respondents... :S :S :S
