Multisite Domain Mapping doesn't work or not activated at all

[avibrazil]

The documentation at 【1】 can't be done on a 4.7.2 WordPress installation, which is higher than the minimum 4.5+ suggested in the article.

When editing the domain, the "Site Address (URL)" field isn't editable.

So either the documentation is wrong (which I doubt) or the native domain mapping function for multisite is somehow disabled on 4.7.2.

The documentation is out of date (so yes, it's wrong). Also it's totally wrong about requiring a dedicated IP...

Just edit the Site Address to what you want, save, done. Tested this on 4.6 and 4.7 and 4.8 and it works :)

So you didn't read me previous post where I said the following:

THE “Site Address (URL)” FIELD IS NOT EDITABLE IN MY FRESH 4.7.2 INSTALLATION. I can see the URL but can't edit it.

So besides de wrong documentation, apparently there is a bug in current WordPress.

Please don't shout. I did read that. That's not what I see on a clean install, unless I'm trying to edit the main site on the network.

Which shouldn't be a question of 'mapping' because you don't map the primary domain on the network. If you're trying to map your primary domain, then that's why you can't edit it, and this is by design.

You're not supposed to change the main domain of your network unless you seriously totally 10000% know what you're doing, because you could very easily break everything.

Multisite can be pretty dangerous. If you change the primary domain you need to use serialization safe search/replace.

You were right. I can edit other domains but not the main. Thank you
