If you want your Mediawiki installation to properly display from the following example subdomain: wiki.bgevolution.com You will need to add the following to your LocalSettings.php configuration file: $wgScriptPath =”"; You will also have to adjust the ANAME records of your DNS server to make sure all subdomains are forwarded to your servers IP address. Use the wildcard (*) and everthing should be find. You will also need to create a name based apache virtualhost to receive the incoming subdomain request. Something like the following works fine: <VirtualHost *> HostName wiki.bgevolution.com DocumentRoot: /home/user/mediawiki/ </VirtualHost>
