MediaWiki: no puedo crear paginas

[keteden]

Hola:

Acabo de empezar con mediawiki, es decir, no tengo ni idea y ya tengo el primer problema.

He configurado la wiki para que no se pueda ver ni registrar (motivos de trabajo) pero no me deja crear paginas una vez que el usuario se ha registrado.

Cuando hago lo siguiente:

Buscar >>NuevaPagina>> Me dice que no hay y le doy a CREAR, me aparece para descargar un archivo index.php ¿?¿?

Os pongo la configuración que he copiado de algunas páginas de internet.

require_once("$IP/extensions/MultiUpload/MultiUpload.php");
require_once("$IP/extensions/FCKeditor/FCKeditor.php");
require_once("extensions/EmbedVideo.php");
require_once("extensions/Googledocviewer.php");
require_once("$IP/extensions/Cite/Cite.php");

#require_once("$IP/extensions/CategoryPermissions.php");
#$wgGroupDefaultAllow=true; //set to true to allow everyone access to pages without a category
#$wgCategoryExclusive=array("Category:cat_name","C ategory:cat2_name");//deny access to these categories for anyone not in the group
