I've been a user of LimeSurvey for many years.
Just recently our IT department implemented load balancing on our servers. After they made this change we started experiencing several issues with LimeSurvey. At first, I couldn't even log in as the admin without being immediately logged out until I enabled table-based sessions by adding the block of code (below) to the config file. Once I did that, I was able to stay logged in but the survey sessions are still being deleted/lost as users navigate between sections.
Can someone please explain to me what I need to change in the config to get this working again?
Do sticky sessions need to be enabled?
The code below is what I added to the config. I'm using Postgres.
Code:
// Uncomment the following line if you need table-based sessions
'session' => array (
'class' => 'application.core.web.DbHttpSession',
'connectionID' => 'db',
'sessionTableName' => '{{sessions}}',
),
),
