Is it possible to disable access to the version
information of MediaWiki?
http://domain.tld/index.php/Spezial:Version
modify the 'Version' field in the array "static public $mList" in
includes/SpecialPage.php :
'Version' => array( 'SpecialPage', 'Version',
'version' ),
and add this in Localsettings.php
$wgGroupPermissions['*' ]['version'] = false;
$wgGroupPermissions['sysop' ]['version'] = true;
So that only admins (sysop) have the 'version' right (needed to see the
Special:Version page)
