Error message when adding a new site

Hi there,

I try to add a new domain to my multisite

And I get this error: "Missing or invalid site address."

The site I try to add is: ""

But: if I type "" in my browser as URL, the browser loads something as if this site now is part of my multisite, please try it, and the browser directs to:

How to add this domain? Is it because of its ending .apartments ?

Thank you

    Hello @harito, I hope you are well today!

    Can you add a domain name without a dot between the words:


    The name of a subdomain you wish to create most likely is the reason you have this error. It’s like you creating a subdomain in a subdomain.

    Would you please ask your host provider in they alow to create a Sub-Subdomain? The wildcart setup may not allow sub-subdomain.

    Please advise.

    Kind Regards,

    Dear Nastia

    Thank you:

    1. entering “lovelyapartments” without the dot worked to add the sub-domain,

    2. heading over to the newly added site, in “domain mapping” I entered “”

    ( .apartments is a new TLD)

    3. loads now as a new site

    4. I could activate Spirit theme

    Upfront does not load when I click on Upfront from the WP-backend, when accessed from the multisite login (I noticed that already with another sub-domain), it only loads after specifically logging in fresh on that subdomain itself, by entering

    Then clicking on Upfront, Upfront loads.

    Hello @harito, I hope you are well today!

    I’m glad that it worked for you and you find a solution by mapping your site with Domain Mapping plugin.

    As for the issue you have with Upfront would you please create a separate ticket? Just to keep things focused in the forum and to avoid confusion from other members that may have similar issues.

    Have a nice day and take care :slight_smile:

    Kind Regards,
