I was following the installation wizard, but I waited a long long time after the installation of plugins to fill the admin creation form and it failed.

• There is a CSS issue with the error box which is too large (we can scroll horizontally within the wizard panel)
• There no action excepted to close the wizard window...

On server side I have :
