[Mediawiki-l] error message MediaWiki 1.7 at 1and1.fr hosting

[Pierre LASSALLE]

Hello,

To install MediaWiki 1.7.1 at 1and1.fr hosting ( http://1and1.fr ) , it 
was necessary to do three things :
1) To rename config folder en configuration folder
2) To place .htaccess with :
AddType x-mapp-php5 .php
3) To begin install giving the right adress in navigator to access to 
configuration folder index.php

After all that, the install message is :
