What is WordPress MU? 

WordPress MU (commonly referred to as Multisite), is now referred to as a "network." Creating a network allows you to create a networks of WordPress sites. Instead of only a WordPress site no yourdomain.com, you can create multiple WordPress sites as subdomains. It allows you to manage all of your WordPress sites from one WordPress Dashboard. Take for instance, you have two completely separate WordPress installations on site1.yourdomain.com and site2.yourdomain.com. You will be able to manage both of these blogs from one Admin page or dashboard.

 

Should I use WordPress or WordPress MU?

WordPress networks do not need to be used on all installations of WordPress. If you only have one instance of WordPress running on each domain your own you do not need to use WordPress MU. However, if you are considering having multiple WordPress sites working on the same domain you should consider creating a network of WordPress website.

Important Advantages

  • Any plugins, upgrade, and themes downloaded will affect all the sites in the network
  • Allows you to have multiple WordPress installations based on one domain
  • Easily allows you to offer blogs to your visitors as subdomains of your website
  • Gives you the ability to manage a clients WordPress site through your Dashboard

How Can I install WordPress MU?

You can install WordPress MU or networking on your account. It can take quite a bit of time to get it set up and working properly though. However, once the network is set up is is quite simple to add more sites to it.

Hello Garr,

Sorry to hear about your problem. Unfortunately, you have given us little or no information about your site, so it's difficult for us to guess the problem that you're having or how to troubleshoot the issue. Also, this article is about Wordpress Multisite in general, it's not a plugin. If you're talking about a specific plugin, please specify the plugin name (Wordpress MU domain plugin is NOT a plugin). Please provide specific information on the issue and we would be glad to investigate the issue further.

Kindest regards,
Arnel C.
