The base URL of the server, including protocol (or protocol relative leading //) and without the trailing slash (eg, "http://www.example.org" or "//mediawiki.org"). See also https://www.mediawiki.org/wiki/Manual:%24wgServer
?>
The PHP closing tag "?>" is never required at the end of a pure-code php file, and mediawiki developers actively remove it, as it often causes problems related to trailing whitespace, and "headers already sent" errors.

ancient
Old MediaWiki versions may have bugs and security vulnerabilities, we don't recommend you to use any release older than 1 year. See http://www.mediawiki.org/wiki/Version_lifecycle for details.
anglebrackets
In PHP prior to version 5.2.9 there is an incompatibility with libxml2 versions 2.7.0?2.7.2. This causes the very noticable issue of angle brackets, < and >, being stripped on Export and Import from Mediawiki. Upgrading PHP to at least 5.2.9 and libxml2 to 2.7.3 OR downgrading libxml2 to a version prior to the 2.7.x series fixes this issue. More info: http://bugs.php.net/bug.php?id=45996

anonnotice
Anonnotice is a wiki-wide message viewable by all logged out users at the top of every page. Similar to sitenotice, if anonnotice exists only logged out users will see anonnotice and only logged in users will see Sitenotice, they will not see each other. Anonnotice is editable by sysops at [[MediaWiki:Anonnotice]]. See also: !sitenotice

To change styles for your wiki, go to one of the MediaWiki:xxx.css wiki page (NOT a file) and put your custom styles there (sysop/admin rights required).

MediaWiki:Vector.css is for the Vector skin (default), etc. For more information, see !skins and https://www.mediawiki.org/wiki/Manual:Interface/CSS
csshideheader
To hide the header on the main page, you need to add this CSS to the wiki page [[MediaWiki:Common.css]]: "body.page-Main_Page h1.firstHeading { display: none; }". If your main page's title is not "Main Page", you'll need to change it accordingly (look at the class on the tag in the HTML source).
