BTW I have set 'public statistics: Yes' in the survey's general settings and in advanced settings for every question I've set 'show public statistics: yes'.
I thought this would at least show the graphs for each question, just like when I view statistics when logged in as an administrator - but all I see is one line showing 'number of responses in this survey: 10' - but no graphs or other data???
Do I need to configure something else to display statistics publicly?
I can work around not being able to use LimeSurvey to automatically generate email notifications (to generate a weekly email with a link to a survey's public statistics) but at the moment I can't even automatically display the statistics for a survey at all.
Any ideas?
