Hey everyone,

I am currently trying to find out about a weird bug I have encountered in LimeSurvey for a customer. We are currently using Version 2.64.7 as far as I can tell. We are about to upgrade soon, but we encountered this error now, which puts a halt to everything. As usal our normal limeSurvey developer is not currently working.

When I open a survey, everything seems normal. It still works when I click next on the first question group. But on the second group this happens:

When the first group had mandatory questions: When I click on Next/Submit on the second group it reloads the first group with validation error of the mandatory questions.

When the first group did not have mandatory questions: It reloads the second group after clicking the Next/Submit Button. SO I can't go any further than the second question group. It doesn't throw any JS-Error. Also this happens on the default template as well.

The installation worked well 2 weeks ago, so i don't know what changed. Also I am at the end of the line for finding the source of this error. I checked every question in the forums, but I can't find any solution.

Thank you for your time.

Without look at the survey itself, I wouldn't rule out a issue inside the survey structure.

Export survey as lss and import survey again (it will be a copy, which should be renamed).
Try again. Same issue? Try to delete parts of the survey. Will the issue vanish or are all parts showing the issue?

Try a different browser as well.

Sorry for not clarifying earlier, but this happens not in this single survey, but all across all surveys present (>200 surveys total). So it can't be a single survey. I suspect something with the installation or something else.

I still tried it out and no result. I also tried different browsers already.

Should mention that single question group surveys are finde and still work

it was working fine. You have not updated the software. Now it doesn't work.
Conclusion: something changed in server configuration, I bet on an update of PHP

Look at your max_input_vars in phpinfo, 2 solutions : cur your second group with less question or put a big number in max_input_vars
