Korogodin/Настройка pretty URL

Задача решена в два действия. --more-- Первое:

В LocalSettings.php:

## The URL base path to the directory containing the wiki;
## defaults for all runtime URL paths are based off of this.
## For more information on customizing the URLs please see:
## http://www.mediawiki.org/wiki/Manual:Short_URL
$wgScriptPath       = "";
$wgArticlePath = "/wiki/$1";
$wgUsePathInfo = true;

Второе

В той же папке в .htaccess добавлено в конец:

RewriteEngine On
RewriteRule ^wiki/(.*)$ /index.php?title=$1 [PT,L,QSA]
RewriteRule ^wiki/*$ /index.php [L,QSA]
