Domain Mapping and WordPress MU

If you’re using this: https://www.ads-software.com/extend/plugins/wordpress-mu-domain-mapping

Make sure to grab version 0.5.4.2

Yup, I’m using the plugin ipstenu suggested. What should I see in the “Domains” tab?

Right now I see this:

Domain Mapping: Domains
Search Domains
Domain:

New Domain
Site ID
Domain
Primary

And plugging in the domains I want to link into any of the fields doesn’t do anything. Once I plugged in another domain and it went to another page that said “Are you sure you want to do this” but there wasn’t any follow up button, and when I refreshed the page, nothing seemed to happen.

What should I see in the “Domains” tab?

This is what it should look like: https://i43.tinypic.com/2hs24c1.png

skibybadoowap – Are you using the right VERSION of teh plugin? This is important ??

Ipstenu, the “read me” file has this information:

=== WordPress MU Domain Mapping ===
Contributors: donncha, wpmuguru, automattic
Tags: wordpressmu, domain-mapping, multisite
Tested up to: 3.3
Stable tag: 0.5.4.2
Requires at least: 2.9.2

It was downloaded through wordpress yesterday.

If I have the right version, are there any other items that would provide these issues? Is there something I’m missing?

Thanks George, mine looks like that, although it doesn’t have any websites under the “save” button. That space is blank.

Is putting domain_mapping.php into the mu-plugins required? As stated before, when I do that the entire website turns “blank”, including the admin and I have to go into the ftp to manually rename the directory for everything to work again.

Likely becuase you haven’t mapped anything ??

Is putting domain_mapping.php into the mu-plugins required?

No, just use Network Activate if you keep the plugin in /plugins/.

Perhaps it’s something to do with the DNS? Here is now I have my DNS setup: OtherIP is an ip that the register originally placed. MainIP is the same IP as the website with the MU admin. My Name servers are all pointing to the same host.

MYDOMAIN.com – MainIP
A – MainIP
mx – OtherIP
mx – OtherIP
mx – OtherIP
mail – OtherIP
pop – OtherIP
imap – OtherIP
* – OtherIP
smtp – OtherIP
ftp – OtherIP
popmail – OtherIP
email – OtherIP
webmail – OtherIP

Does all of this look right?

Update:
Apparently I have been foolish and didn’t insert a Site ID for each new website. I’ve done that now, and I have mapped all my websites, but they are not showing up in the “Sites” tab. I assume the DNS takes a while to change over? Is there anything else I need to setup?

DNS *shouldn’t* have anything to do with that (ie mapped domain names appearing under “Sites”). If there’s problem with your DNS setup, the pages simply wont load, but the proper info should appear in WordPress.

Note that you can also do the domain mapping from the individual sites / blogs, rather than the network dashboard. Try that and see if it makes any difference (Tools => Domain Mapping)

DNS can take up to 72 hours, depending on what you set your TTL to.

That said, they should show up right away in Sites…

I have a dozen domains each with different site IDs on the “Domain Mapping: Domains” but none of them are showing up on sites. Is this a DNS problem, or an install problem?

Under the “sites” tab, when I click on new site, I get this option:

Add New Site
Site Address .MYDOMAIN.com

Only the characters a-z and 0-9 recommended.
Site Title
Admin Email
A new user will be created if the above email address is not in the database.
The username and password will be mailed to this email address.

But I’m not able to add any full domain, just subdomains, is this functioning correctly?

Okay.

1) Add a subdomain to your site sitname.MAINDOMAIN.com
2) MAP newdomain.com to sitename.maindomain.com via the plugin

Are you doing that?

Here’s the long-winded version of what Ipstenu succinctly said in just two lines.

You appear to be solving two problems at the same time, and that makes it difficult to know exactly what is working and what is not.

First forget about domain mapping (just for now). From the preceding, I assume you have a sub-domain setup. From WordPress, create a new sub-domain site sitename.MAINDOMAIN.com (if you haven’t done so already).

Does the sub-domain site you created above work? Are you able to access both the front-end and the WordPress dashboard for this site? If not, you have a problem with your DNS or Apache setup. Get this fixed before you move on.

If the sub-domain site works fine, now is the time to MAP a new domain onto the EXISTING sub-domain site (it’s called domain MAPPING plugin for a reason). Login to the dashboard for the sub-domain site, and go to Tools => Domain Mapping, and enter the new domain that you want to map unto this sub-domain.
