Domain Mapping: Domain Name Is Unavailable To Access

I have a client running a site under my MU installation. The site is It was working until a day or two ago when my client accidentally deleted the DNS records we had set up for her. Now I attempted to recreate what I believe are the correct DNS settings, but I can not get the domain mapping to work correctly for the site.

I’ve checked and the site itself works fine as a subdomain of ( works fine). I have set the A record for to point to the IP address of The TTL is a half hour and it’s been well over an hour and still no joy: every time I attempt to map the domain, I get the “Domain Name Is Unavailable To Access” warning and can’t map the domain. I’ve also checked the DNS at and it’s showing the updated IP address. So it looks like the DNS entry has populated. Moreover, the error page is a Dreamhost error page (which is where the site should be hosted), so it seems to me like the A record has propagated but for some reason I still can’t map to it.

Any ideas? I’m at a loss for what to try next.

    Hey Eric,

    Hope you’re doing well today and apologies for the delay!

    Since it is so old, there could be an issue with the sunrise.php file.

    Can you delete the one in your /wp-content/ folder then copy over the new one to that folder from /wp-content/plugins/domain-mapping/

    this should update automatically on updates; however, since you were updating from such an old version it may not have.

    If that doesn’t fix it, then can you send in your FTP and WP login, that way I can take a closer look.

    You can send that privately through our contact form:

    Select “I have a different question“.
