installation sur serveur 1&1

Bonjour,
je suis novice 

j'essaye d'installer piwam sur mon site hebergé par 1&1.
je décompresse l'archive, modifie l'accès aux dossiers (cache - logs- 
database.yml)et quand je lance piwam/web/index.php, la page reste blanche.
j'ai modifier le htaccess comme suis:
Options +FollowSymLinks +ExecCGI

<IfModule mod_rewrite.c>
  RewriteEngine On

  # uncomment the following line, if you are having trouble
  # getting no_script_name to work
  RewriteBase /

  # we skip all files with .something
  RewriteCond %{REQUEST_URI} \..+$
  RewriteCond %{REQUEST_URI} !\.html$
  RewriteRule .* - [L]

  # we check if the .html version is here (caching)
  RewriteRule ^$ index.html [QSA]
  RewriteRule ^([^.]+)$ $1.html [QSA]
  RewriteCond %{REQUEST_FILENAME} !-f

  # no, so we redirect to our front web controller
  RewriteRule ^(.*)$ index.php [QSA,L]
</IfModule>

database.yml :
ligne 30  prod:
  .settings:
    no_script_name:         on
    logging_enabled:        on
si je tape amac84.fr/piwam/
