Support » Networking WordPress » Why can't a WordPress network (multisite) in it's own folder use subdomains?

  • Resolved DaveE


    If I’m setting up a brand new multisite installation with WordPress in it’s own folder (say /wp/) why can’t I configure the network to use subdomains instead of subfolders?

    Currently, if I try to setup the network with the WordPress core in it’s own folder I’m not allowed to choose between a subdomain-based or sub-folder based network. I must use sub-folders.

    What are the technical reasons for this? I’ve scoured trac and Google for an answer to this question with no luck. A more detailed explanation than what is provided on or would be greatly appreciated.

    Hi Ipstenu,

    I mean the former and actually figured this out thanks in part to your response. It was a simple oversight.

    I setup a clean install of WordPress using Mark Jaquith’s WordPress Skeleton which places WordPress’s core files at However, when trying to run install.php, WordPress chokes on it’s own redirects in this senario (maybe a bug report for another day).

    To get around that, I manually typed in the correct path to install.php: By doing this, WordPress automatically set the home URL to instead of just (Doh!) By changing the site’s home URL to, I am now able to choose a subdomain or subfolder installation when setting up the multisite.

    Thanks for your help and getting me pointed down the right track. It’s much appreciated!
