[Drupal] Activate clean urls with 1and1 host

If you can not activate clean urls, and your site is hosted in 1and1 servers, you have probably to modify the .htaccess file in your site root folder, to the following :

# Various rewrite rules.

  RewriteEngine on

  # Modify the RewriteBase if you are using Drupal in a subdirectory and
  # the rewrite rules are not working properly.
  RewriteBase /sitename # PUT YOUR SITE NAME (FOLDER NAME) HERE

  # Rewrite old-style URLs of the form 'node.php?id=x'.
  #RewriteCond %{REQUEST_FILENAME} !-f
  #RewriteCond %{REQUEST_FILENAME} !-d
  #RewriteCond %{QUERY_STRING} ^id=([^&]+)$
  #RewriteRule node.php index.php?q=node/view/%1 [L]

  # Rewrite old-style URLs of the form 'module.php?mod=x'.
  #RewriteCond %{REQUEST_FILENAME} !-f
  #RewriteCond %{REQUEST_FILENAME} !-d
  #RewriteCond %{QUERY_STRING} ^mod=([^&]+)$
  #RewriteRule module.php index.php?q=%1 [L]

  # Rewrite current-style URLs of the form 'index.php?q=x'.
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
