The '/admin' of limesurvey is not working.
I've tried on the Azure Cloud and on my AWS Account, but I can't login.
I've been able to reproduce it. It seems a bad configuration. While we work to fix it, you can use /admin/admin.php to access the administration panel.
Thanks for reporting it!
Try to do the following modifications in your config.php file
'urlFormat' => 'get',
'showScriptName' => false,
'urlFormat' => 'path',
'showScriptName' => true,
Let us know if it worked for you!
