We have a survey that we use repeatedly with minor question changes (open, no tokens). To facilitate this, we create a new survey each time by copying the last survey. We then alter some of the questions, activate the survey and send it to our members. However, we are getting a number of complaints from users of Chrome (Windows/Linux and Mac).The user fills in the first group of questions, clicks next and the page reloads the first group, with no answers filled in. If, when filling in the first group of questions, the user misses a questions, they get the expected popup and error message about a required field not filled in. We've tried different templates and re-installing LimeSurvey. The only way to get the survey to work in Chrome for these users is if they access the survey in Incognito mode, or by wiping out all cookies for the site the survey is installed on. Other browsers work fine on the same survey (Firefox, Safari, Edge). I can replicate the issue here as well.

Is there some trick to getting a Survey to work, that is made from a copy?

- None of our groups have conditions set on them that I can see.

- About the only trouble shooting I can figure out to do is looking at the POST request differences between Chrome normal usage and Chrome Incognito mode. Most notably, they YII_CSRF_TOKEN is very different:

Chrome normal mode token looks like this:

< YII_CSRF_TOKEN:56257410797c2a64b39944d39e6e2fffd01ff4e5

Chrome incognito mode token looks like this:

> YII_CSRF_TOKEN:VmNGYk2WWVRDVmxXcXpybmZvRVRveVJkalFucW0yU3eD_TJJWE3W_2gwWxYnPzbxg0pom6DM9YuTEDyO-bFlsQ==

Any suggestions would most helpful. Happy to send the link out if someone wants to look.

?????? Start by limesurvey version and build number + activate debug mode manual.limesurvey.org/Debug_mode

My apologies for not including the pertinent information and for pointing me to debug mode, I had missed that before.

For the record:
Version 2.67.3+170728
Running on Apache 2.4 and PHP 5.6

Did you try with a more simple survey ?

Tough to test, as we don't know why some people have this and some don't. But yes, we have 5 other surveys that all work fine. Some are quite complex with various groups and conditionals.

I've tried debug=1 and debug=2 but so far there are no errors or warnings in our php error log nor apache log.

Next Step: Made a new copy of the survey, delete all questions and all groups. Added 2 groups: Group1 & Group2. Added one long text question to each group for a total of 2 questions.

Ran survey in Chrome: I can't get past the first group.

Create a new survey without copying: 2 groups, 1 long text question per group. Also can't get past group 1.

Again, only in Chrome normal mode. Incognito mode the survey runs fine.

This is really strange : we never have issue with Chrome before : some of our dev use Chrome. (personnaly only chromium or icecat).
Can you create a bug and send the last css file (the one with 2 groups and 1 long text question)? www.limesurvey.org/community/bug-tracker
