I have discovered the issue, which is caused by the sortable in questionEditor.js. I have temporarily dealt with it and did not use sortable when the answer item is greater than 500.

I like to check this on 5.X

Can you upload a lss file and not a lsq ?

Please check LSS

Thank you !
Same with LimeSurvey5

Awfull … near 30 seconds to get the page.

A 3.X version.

On 3.X : edit question is OK
Edit answers take time (maybe a little less than 5.X) but seems more clear.

When my options were 2000, it would take at least 5 minutes for the page to render, so I just temporarily processed it and no longer used sortable if it was greater than 500. I'm not sure if there is a better solution

My opinion here :

1. When you try to edit X000 answer : seems a good solution to deactivate sortable. Maybe allow to activate it via a button ?
2. Have 1 minutes for edition 2000 answers : can be understandable, but not when edition only the question : answer + subquestion must be loaded only if needed and saved only if neeeded (there are other reason for this)
