Thanks for this excellent plugin. It's easy to use with plenty of useful features for survey purposes.
One problem I have is that I can't seem to make the questions random in appearance even though the "display question random" option is activated. Our survey has 5 categories with each category having 10 questions each. Each category tends to cluster together in their order of appearance (eg. question 1-4 are of Category A, question 5-7 are of Category B).
I have manually moved them around in the "Questions" section and also recreated a new quiz with random order of questions from each category but they made no difference the final quiz always ends up with questions from same category clustered together.
Ideally the quiz should be random in category appearance with question 1 is of Category A, question 2 is of Category C, question 3 is of Category D, question 4 of Category B, question 5 of Category 1 again etc.
I would really appreciate your help to solve this problem. Thank you in advance.
Note: we use WordPress 3.6.1. Questions are all in one page below each other format.
