After updating to v3, when you attempt to use the numbered pagination controls at the bottom of the survey participants list you get an exception in the console
Code:
GET https://www.domain.com/index.php/admin/survey/sa/datetimesettings?YII_CSRF_TOKEN=xyz 404 (Not Found)
which leads to:
Code:
Uncaught TypeError: Cannot read property 'jsdate' of undefined
which results in pagination javascript controls not working.
We are not using any proxy or caching software. Worked before upgrade to v3.
You might open a bugticket. From what version did you upgrade to what version of LS 3? Currently there is no upgrade path to LS 3 approved by the developers.
