Can MU be installed in a sub-directory and still use Doman Mapping?

My main domain is and my sub directory is, which is the one with MU installed on it. Can I use the Domain Mapping plugin on the domain or do I have to make it the main domain?

    Hey Whit,

    I hope you’re having a nice day and thank you for your question!

    Our Domain mapping plugin should work fine with sub-directory install. I’m a bit confused though with the relationship of your domains/sites. Could you explain it a bit?

    Assuming that you have your WP installed under “” as a sub-directory install, then all the sites will have URLs like these “”, “” etc.

    Our plugin should handle such setup just fine.

    The same applies to this scenario: a sub-directory install on subdirectory, so the main site is at “” and sub-sites are “” etc.

    However, I’m not sure what’s exactly “” in your example. I admin I’m a little lost here :slight_smile: Please advise and I’ll be glad to help you set this all up.

    My current set up is “” but I want to use the domain mapping plugin to allow user to set up their own domain to reach their site.

    They set up then they add their own domain with the domain mapping plugin. Is this possible or do I have to have my wordpress installed on the rooted directory?

    My main domain for my server is and the wordpress set up in as an add-0n domain

    Hey Whit,

    thanks for this feedback!

    The clue here is that if you can setup your “domain to be mapped” on your server to load your main site (which would be then you should be good to go. Depending on your server’s/domain’s config this can be achieved either by using a dedicated IP and setting its “DocumentRoot” to point to the same directory as your main domain or by setting CNAME record to point to your main domain.

    So, once you’re able to load your main site with “domain to be mapped” (even if the site would seem “broken” at first glance), the Domain Mapping should then work fine I think.

    Kind regards,


Thank NAME, for their help.
