What is the mu-plugins folder?

Users of WordPressMU have long been aware of a folder within wp-content called mu-plugins. Obvious conclusions were drawn because of the name and where it was, but this actually stands for “must-use” plugins. Why? Because any code (plugin) placed in the folder is run automagically, as if...

Everything you wanted to know about creating a network of multiple sites in 3.0

While the basic of Creating a network are in the codex, there are a few extras that it’s hard to know exactly where to put them. Before you embark on this new feature, I figured I’d have a one-stop resource page for all the fiddly little bits you need to know. And after I’ve been working...

Upgradephobia

Here you are, your website is all done, launched and you have a stream of visitors stopping by on a regular basis. Great! That hard work of adding in all these plugins, special themes, some custom code – it’s all paying off finally. Then one day you login and there’s that yellow upgrade...

Must use plugins and 3.0

If you have been testing out the beta of WordPress, and are new to the whole concept of multiple sites, you may have noted a lot of the wordpress-mu-specific plugins make reference to the mu-plugins folder. This is not created by default. You must create it in the wp-content folder. The “mu”...

Forum cheat sheet

As the merge comes closer, the forums are winding down. Most of the time, I’m only answering threads that I can do immediately without digging up additional info. That means I also repeat myself quite a bit. In the interest of making sure all those answers are in one place, here’s my cheat...

How to backup WPMU

Backup. Everyone tells you to, but maybe you don’t know how. After all, your host does backups, right? True – your host does backups, but can or will restore only in the event of a complete disaster, and it restores the entire web account. You should very much take your own backups and store...

The site admin menu

It’s been a while since we had a new admin area, and my old post with site admin panel screenshots is now horribly outdated. So! If you want to look before you leap into the wonderful world of WPMU, here’s some Site Admin screenshots. Most of the admin area looks exactly the same as regular...

DNS Explained

The purpose of the DNS (Domain Name Server) system is to give client computers a means of translating host names (ex. wpmututorials.com) into IP (Internet Protocol) addresses. In a typical day of working my browser(s) submits hundred of queries to my DNS servers to get the IP address of the web sites...

Picking the right web host

In today’s post, I go over the types of hosting available and break them down so you can make the right choice for you and your setup. Before we get into the nitty-gritty, the biggest point I want to make is make sure you get a Linux-based hosting package. WPMU runs under Apache and it also uses...

Small Optimization

If you have been running WorPress MU for a while, you may not have seen some of the recent additions to values defined in wp-config.php. For single site WPMU installs, as of 2.6.1, you can save a couple of database and/or internal cache lookups by adding 3 defines to your wp-config.php: define('DOMAIN_CURRENT_SITE',...
