Personalize MediaWiki

Move the installation directory

The MediaWiki does not record the installation path in the database. If the directory is moved or changed, just simply update the $wgScriptPath in the LocalSettings.php file.

$wgScriptPath       = "/wiki";

Hide tabs

Reference: http://www.mediawiki.org/wiki/User:Subfader/Hide_page_tabs
This is to hide a tab on all pages. Note that hiding tab does not prevent from accessing the page.

• Update MediaWiki:Common.css.

/* Hide [Watch] tab */
#ca-watch { display: none !important; }

/* Hide [History] tab */
#ca-history { display: none !important; }

/* Hide [View Source] tab */
#ca-viewsource { display: none !important; }

/* Hide [Discussion] tab */
#ca-talk { display: none !important; }

Change Favicon

Reference: http://www.mediawiki.org/wiki/Manual:$wgFavicon
Use the free icon generator web site like http://www.favicon.cc/.

Use Google AdSense extension

Use Short URL

http://www.mediawiki.org/wiki/Manual:Short_URL
http://www.mediawiki.org/wiki/Manual:Short_URL/wiki/Page_title_--_PHP_as_a_CGI_module,_no_root_access
Sample of the default page address is

http://website.com/wiki/index.php?title=Page_title

The Short URL version of above is

http://website.com/wiki/Page_title

Sample here is for 1and1 hosting using PHP as a CGI module with no root access.

• Update the LocalSettings.php.

$wgScript           = "$wgScriptPath/index.php";
$wgRedirectScript   = "$wgScriptPath/redirect.php";
$wgArticlePath      = "$wgScriptPath/$1";
$wgUsePathInfo      = false;     

• Update the .htaccess file in the web root where the MediaWiki is installed.

AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /wiki/index.php?title=$1 [L,QSA]

Note that AddType and AddHandler are added because by default 1and1 will handle the .php file with PHP4 - http://faq.1and1.com/archive/44.html

Add custom error-landing page
