Where can I find information about changing the session timeout for a survey? Some of our users leave the survey open for 2 hours or so then when they come back they loss all there progress.

I through that setting the MySQL -> "settings_global" -> "iSessionExpirationTime" to 172800. Would keep the sessions open for 2 days but this was not the case.

Perhaps the Yii framework controllers this and I should read there?

have a look at application/config/config-defaults.php file

( search for " iSessionExpirationTime ")

We use iSessionExpirationTime ONLY if you set session to DB in config.php.

If not : you must use server part (virtual host config) to allow so long session.

If you can't : framagit.org/SondagePro-LimeSurvey-plugi...lob/master/README.md or github.com/frederikprijck/limesurvey-plugin-heartbeat

Thank you as well this is helpful.

Hi Ben
Where do we enter in the PHP code (to find the file you mentioned)?
I want to increase the time before session expiration...
thank you

You enter the PHP code in this file <place where limesurvey is installed>/application/config/config.php

in the return array there is a 'config' array and you want to add the following into that config array
'iSessionExpirationTime' => 172800,

of course replace that number with what ever you want.

Yes thank you !

Hi,

I do have V 3.17 and a some issue with timeout for people using the survey. How can I make it longer ?
When I add 'iSessionExpirationTime' => 172800 for example in the config.php - Impossible to start any survey again "white page"

Any Idea ?

Best regards,

Hello @jpperrein,

Please create a new topic and provide as many details as possible about your server configuration.

I come back to this old topic with a question of beginners. If i modify 'iSessionExpirationTime' in the config.php, will the change be made for questionnaires already activated?

Thank you in advance for your answer

The session settings are global.The session is not done surveywise. So it would apply to every survey. But the setting only works if sessions are done via DB. Filebased sessions are controlled via php.ini
