Install staying at step 2/2

Hi !

I try to install SuiteCRM for a little company where I work because we don’t have good tools (2 peoples only). Unfortunately I can’t finish the install and I don’t know why :’(

I read the install guide so I copied SuiteCRM files to my local web server.
Then I set ownership of the CRM directory with http:http because that’s the user of nginx in Arch
I also set the permissions on the CRM directory
sudo chown -R www-data:www-data .
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload config_override.php
At the end, I go to

There I can accep the license and on the next page, all the systems environnements are OK so I click to the Next button to go to the “Step 2 of 2 - Configuration” screen

If I clic on the Next button without complete the fields, an error occurs: “Administrator Email Address is incorrect.” Once I put something in the email adress field and I clic on the Next button, nothing appends. Even if user/password are set or not, same as Admin user.
