How To Add PHP5 If You Use 1&1 For Web Hosting
With the intro of WordPress 3.2 you will need to be using PHP5 but 1&1 uses PHP4 as a default so to upgrade to 5 you just need to add the line AddType x-mapp-php5 .php to your .htaccess file. So when you look at the file it should look something like this.
AddType x-mapp-php5 .php
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
