I have 23 subquestions in an array and after the first 20 the category/column titles for the answers appear again in the middle of the array. Can I get rid of them?

The amount of subquestions when this appears can be set in general settings. But 23 subquestions is a lot and people will forget about the scale if they can't see it on their screen anymore. So I would recommend to leave it there, but show it before (like after 12).

Here is where you can find this in LS 2.5:

Go to "Configuration" --> "Global settings"

Here a screenshot:

Hi! Thanks for the answer. Unfortunately I am using Limesurvey through my McGill University login and the site appears to use version 1.92+. I don't see that option under General settings/Presentation & navigation. Is there a workaround?

This should be available in 1.92 as well, if I remember right. However, as you use the installation of a university, you most probably don't have access to the installation level settings, where this should be located at. You probably only have access on the survey level.

However, I can't believe your university is still on 1.92, which means that they have not updated Limesurvey for at least 4 years! This version has not received any security updates since 2012 (if I recall right) and should not be used in an productive environment. I would highly recommend to update to 2.06 (I personally would still wait a bit with 2.5). And it is not only about security. Limesurvey has improved a lot since then and it is worth to upgrade.
