Provide a litlle lss file showing this issue.

And remind : with only 2 answer you have good chance to have same order

I uploaded the file now. I know hat the chances are good to get the same order,but I tried it a couple of times. Kind Regards

We have:
SELECT * FROM {{questions}} WHERE parent_qid=12884 AND language='de' ORDER BY RAND()

Then sql issue .

This part is for dev i think (do the select without rand to have SQL caching).

<quote>RAND() is not meant to be a perfect random generator. It is a fast way to generate random numbers on demand that is portable between platforms for the same MySQL version. </quote>

I can reproduce this issue but independently of the number of answer options.

Maybe we are just treating this wrong and the feature was meant to randomize the subquestions and not the columns?!

@Nambu, can you please attach the sample survey as LSS file with the question that worked fine for you?

@Mazi :
Yes sub question (for a while):
SELECT * FROM {{questions}} WHERE parent_qid=12884 AND language='de' ORDER BY RAND()

Yes, this is a misunderstanding. Randomize answers does mean subquestions in this case. I updated the documentation and will change the label text, too.
