Getting help: Useful For Users or Waste of Space?

Let’s say you’ve just installed WordPress for the first time and you’re a bit confused about the admin area. What are posts as opposed to pages? Is the tools section the same as the settings section?

It’s easy for newbies to feel just a little bit overwhelmed. So what do you do? You click on the help drop down menu, of course. You know the one, it’s in the top right hand corner? You click it and it drops down and there’s text and stuff…? Yeah, I haven’t used it either.

One of the scariest things a developer can hear from a new client is the infamous claim: “I know just enough to be dangerous.” Translation: I don’t really know much but I sure love to tinker with things! This always puts up a little red flag in my mind. However, a seemingly harmless bit of tinkering can have disastrous consequences on a live website.

Merge WordPress Tags Easily and Quickly for a Leaner, Better Site

In a way, tags in WordPress are like categories. They are meant to group similar topics together in a way that makes them easily accessible (i.e. by clicking on a tag link and seeing all the posts marked with that descriptor).

The problem a lot of people run into is that they end up assigning too many tags to their posts. This defeats the purpose of tags. If you only end up with one or two posts with that tag, it hardly deserves its own “category.”

WordPress Multisite with Nginx – How to set it all up and enjoy the blazing fast consequences

Recently, due to the many attacks launched on the internet, especially the botnet DDoS attacking WordPress hosts, I was forced to move some of my sites to a shared server — a virtual machine — with little memory and just a slice of one CPU core.

This required rethinking the whole strategy of hosting them: instead of having huge server with almost unlimited memory, disk space, many CPU cores, and infinite resources, I had to somehow extract the same amount of performance out of this tiny virtual server. How?

How To Quickly Duplicate A WordPress Database

There are many situations where you may need to copy your WordPress database. The most common scenario would be to set up a development site in order to test new themes or features. In the past you may have exported a copy and then re-imported that to a new blank database. If you want to copy your database onto the same server, then this is probably the easiest way.

This quick tip is based on a phpMyAdmin operations feature, so it won’t apply to you if your host is using something else for managing databases.

How to Make a Command Line for Your WordPress Site

Are you that level of WordPress user that could use the WordPress back-end blindfolded (figuratively of course)? You know – that user who is so fluent that doing simple tasks in the administration panel are irritating because it’s too slow? That user who maybe knows HTML and possibly even CSS but doesn’t want to venture into hardcore coding?

Importing & Exporting WordPress Sites To and From a Multisite Install

One of the most common questions about using WordPress Multisite is, “Can I import an already existing site into Multisite?”

Similarly, another common question is, “Can I peel off a site on a Multisite install and turn it into a single installation?”

The answer to both of these questions is yes, and we’re going to go through how to do that in this post. Essentially it’s as easy as using the Import/Export functions found under the Tools menu in your WordPress admin area.
