Error 500 wordpress 1and1

Using one and one hosting, I wanted to install WordPress. I had an Error 500. Too Bad. Here is the trick :

Check that your root .htaccess file has the following information :

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php

Don’t forget to save it with UNIX Line Endings (thanks to NotePad++ on windows for example), in UTF8 and after removing all special characters. (Squares, with Windows)
