I need your help please... After upgrade from 2.2.3 to 2.2.4 I got blank page when I click on Web Setup Wizard in System>Tools> Web Setup Wizard. It was working before upgrade.
This was the Solution in my case
Go to public_html/app/etc/env.php and change the following code from
'session' => [ 'save' => 'db'
'session' => [ 'save' => 'files'
