Hi

Sometimes when testing the "Resume" functionality, the saved survey is empty, i.e. the user clicks the links sent by email - the survey opens but with no answers registered from last use.

This happens inconsistently - and maybe once every 8 or 9 tries.

The survey is not very big, but e.g. the first question is a multiple choice question with 100 checkmarks. When testing I tend to be very quick. So my hypothesis is that its a matter of setting cache:false in the header? Or maybe the page is not actually finished loading when I click "Resume" button? In that case a solution might be to hide the resume button with display none for a few seconds?

But I would very much like to know, if anybody has hints to what could be causing this situation.

sincerely

For the record we are using php 7.2 and postgresql 10.6

Is it possible that we should try another setup?

Try disabling AJAX in the survey theme options. This will cause only single pages to be loaded at a time instead of the whole survey.

That would also mean I'd loose some functionality? E.g. question 8 is only shown if question 6 == "Yes". This works now - but if I disable ajax, I have to create to survey groups ans present questions group by group?

No, relevance should work with or without AJAX.

Also on the same page? If AJAX setting is only meant for background data processesing and if it can create problems , shouldn't it be disabled by default?

I am trying to understand what the trade off for me will be, and what new issues might arise.

Will see what happens.

As I understand it, the only issue may be slightly longer load times but I have not noticed the those.

I disable AJAX in all of my themes - I have seen too many issues with my clients and here in the forums to trust it.
