Hi

after several problems on a 1and 1 (1&1, 1und1) server, I installed their 1-click-app of C5 (version 5.4.1.1 is being installed at this time).
By doing this the automatic installation process creates a .htaccess file which you can use for your own C5 installation as well!
(see also the php.ini you get with this type of install from 1&1, posting: )

Here the code:

AddHandler x-mapp-php5 .php
AddType x-mapp-php5 .php
Action x-mapp-php5 /system-bin/php5exe
