we have updated our limesurvey hosting from version 2.71.1 to version 3.2.0 and then we have tested our surveys and we have found a problem in exporting the responses to PDF file.
In version 2.71 the survey PDF file includes only the questions with an answer, but now in version 3.2.0 (and also in 3.3.1) the PDF also does include all the questions without an answer! Because of our survey has hundreds of questions the PDF file from about 20 pages now exceeds more than 85 and another survey from 25 pages now exceeds 600 pages!!
This is a problem for us because our partecipants want to print a PDF copy of the survey.
Can we set a flag to limit the PDF file to only questions with answers or how can this problem be solved?
