  • How do I map a blog to the domain I want?

    I have WordPress 3.3 (not 3.3.1 yet), installed in /public_html
    I have the dev version of the Domain Mapping plugin, 1/7/2012

    I am using the subdomain multi-site installation of WordPress (not sub folders)
    I have wildcard DNS working; when I create a blog, WP creates a subdomain for it.

    I have a domain name as a subdomain, pointing to /public_html/glerner
    I have a domain name for WordPress, pointing to /public_html

    I want to change the default

    I have this working for another blog. There used to be a page for specifying the mapping.
    Now I can’t find how to map the blog to the domain I want (a change in WP 3.2 or 3.3 menus?)

    If I simply Edit the Site (/wp-admin/network/site-info.php) and put what I want in the Domain field, the blog displays with the address I want ( but I am unable to log in to /wp-admin (I am brought back to the login screen). [I didn’t think it would work, but it’s all I can find to try].

    The only Domain Mapping instructions (once the plug-in is installed) that I can find are for previous versions of WordPress.

    The only Domain Mapping instructions (once the plug-in is installed) that I can find are for previous versions of WordPress.

    The instructions for the current version of WP are the same as for WP 3.1.Other than bug fixes the plugin hasn’t changed in about a year.


    The readme.txt mentions “Tools->Domain Mapping where they can add or delete domains.”

    I don’t have that menu any more.

    There used to be a screen for doing the actual mapping (once I have added a domain in WordPress, which blogs do I want mapped to it). I can’t find that screen now.

    The blogs that I mapped before are still working, but I can’t map a new blog.

    I have My Sites, Network Admin, Dashboard (
    from there, Settings, Domain Mapping, Domain Options
    from there, Settings, Domains

    But where do I say to map a single blog to a domain I put in Domains?

    Network Admin -> Settings -> Domains

    You have to have a sub site to be able to map a domain.

    Alternatively, you can turn on the user DM page which appears in the Tools menu on the subsite.


    I do not have a Network Admin -> Settings menu.
    I’ve looked from my main domain’s wp-admin, and from a mapped domain’s wp-admin

    I do have subdomains, and WordPress installed in subdomain mode.
    I have several sites set up.
    I have old sites where I mapped (e.g. ) but can not map new domains.

    Did you create a network in your WP install?

    Ron, I don’t understand.
    I have WordPress running multi-site, subdomain mode.
    I have wildcard DNS, so WordPress creates effortlessly.
    I have 19 sites created in the one WP installation.
    That’s what I think of for “create a network”.

    WP was installed so I could map, for example, to (where is a subfolder of public_html and WordPress is installed in public_html)

    Now I can’t even find the screen for specifying that mapping.

    If you have WP 3.3(.1), hover on the My Sites. When the menu drops down, click on the Network Admin link.

    Also, you cannot use domain mapping to map other WP installs into your network.

    Only one installation of WP on my server (and not trying to map WP installed another servers into this network).

    OK, My Sites, Network Admin. I have Dashboard, Sites, Users, Visit Network
    Now what?

    In Sites (, there is a column “Mapping” but no way to specify mapping.

    I’d like someone to write instructions. Instead of “RTFM” I’m asking “where is …”

    After you click on Network Admin (not a submenu item under Network Admin) you should be able to get to see this screenshot by clicking on the Settings menu item

    Ron, everyone,

    Instructions Please!

    Yes, Ron, I see those menus. In Network Admin, I have Network Settings, Network Setup, Domain Mapping, and Domains. (I don’t have any Sitewide Tags menu item.)

    But How Do I Use them? What do I put in each field, to get domain mapping going?

    Are there settings in other menus? Seems like there would be changes in Sites as well.

    Instructions, please!

    lernerconsult – Take a deep breath.

    You’re over thinking some of this. Click on the link for ‘Domain Mapping’ and look at the page. What’s it asking you?

    It looks like this: right?

    You can read this:

    Some of the locations of the menu are out of date, but it should help.

    Keep in mind, we can’t tell you what the answers are, since everyone’s IPs, domain names, and choices, are going to be different.


    I’ve seen the OttoPress tutorial. It’s good, but either leaves out some steps, or leaves out a few details I need to get it right.

    I’ve done “Manual Plugin Installation”, “Activate Sunrise”

    In “Server Info”, the Domain Mapping Configuration screen, I have the domain name for my WordPress 3 installation, without leading http://www. in Server CNAME Domain (example: I have “Permanent Redirect” and “User domain mapping page” checked (none others).

    In “Mapping the Domain” I do not have what he shows. All I have is “Add new domain”.

    I have
    I want it to be
    I put “” in “Add new domain” and get “New domain already exists.”
    So, what else do I have to configure to get it working?

    Are there settings in Sites, Edit? Most things I’ve put in the Domain field (with or without “Update siteurl and home as well” either make the blog fail totally, or have it display with the URL I want, but logging in fails in an endless loop.

    OttoPress says “The other way to set domain mapping is through the Super Admin->Domains menu. Here you’ll find a list of sites and their ID numbers. You can map an id number directly to a domain name here.”

    In Network Settings, Domains [I’m guessing this used to be Super Admin->Domains], what do I use for Site ID? Never seen any documentation for this field. What do I put for the domain? (

    Did you already map is a SUBDOMAIN, not a top level domain. Try putting that in, instead.

    WordPress is installed as, multi-site in subdomain mode, and is working.

    I have a non-WordPress web site,, on the same web hosting account.

    “Did you already map” is ambiguous. Did I “map a blog to”? That is what I’ve been trying to get working… so I have to say “no”. If you mean by “map” “does display a web site?”, then yes.

    “Try putting that in, instead”. If you mean “did I put in the Domain field”, yes I’ve tried that. If you mean “put in the Domain field” I’ll try that.

    I want a WordPress blog, mapped from http//

    /wp-admin/network/settings.php?page=dm_domains_admin asks for a Domain; when I put there, I get “New domain already exists.”

    /wp-admin/tools.php?page=domainmapping asks for a Domain; when I put there it appears to take it, but the mapping doesn’t work: brings me to

    Someone who has this working on their site: what specifically did you do? What values did you put in which fields, to get your mapping working?
