One-Click Child Theme

Adds a Theme option to any active theme allowing you to make a child theme.

I already modified my CSS in the existing theme? How do I use One Click Child Theme to fix this?

You can wait for the theme to get updated and have it break it, or you can:

  1. Go through the steps for installing and running the plugin above to create a child theme
  2. Click on the Appearance > Editor in your admin dashboard menu (or network admin menu if multi-site).
  3. Select the parent theme in the drop down on the right, click Select and make sure you are editing the file style.css (select on the right).
  4. Copy the changes you made, if you managed to remember them.
  5. Select the child theme you created to the drop down in the left (you should be editing style.css).
  6. Paste your changes to the end of the file.

Your plugin broke my site!

I didn't think that's possible, but if so, I want to fix it!

First, check what really happened. Is your admin console broken, is the theme broken (go to a new window and check your blog). If a theme fails to work and for some reason I didn't catch that error, WordPress should restore the previous theme (or whatever the default theme is) so your actual blog should be okay and recoverable. If for some reason it didn't default to the right theme, go into the Appearance menu and re-enable the parent theme.

Then go to the support page, describe what happened (screenshots help too) and anything else and we'll try our best to help you.

I can't find this Theme Option button you are alluding to in the documentation?

I really need to update the screenshot. It's still there, but the location has changed as WordPress has been upgraded.

  1. Go to the Appearance tab
  2. Click on the Active theme (it should say "Theme Details" when you mouseover)
  3. An overlay appears. The Theme option button "Child Theme" is there

When I go to the Child Theme menu, it says "X is already a child theme" and I can't create a child theme.

Making grandchildren of themes is non-trivial, so I disabled the form if it is already a child theme. Instead I offer the ability to repair the Child theme or copy template files from the parent into the child for editing.

Can the plugin be deleted after I create a Child Theme with it?

Yes. The main purpose of the plugin is fulfilled. Congratulations! (Personally, I'd disable it, instead of delete it.)

Having said that, there are some things that this plugin help with after your child theme's birth. Think of it as a parenting guide for your new child theme.

Features like?

  • Repair a child theme created in the old style.
  • Copy templates over from your parent theme into your child theme.
  • Replace the child theme screenshot with one of your site

When you have an active child theme, click on Appearance > Child Theme to get to these functions.

What does the "Repair Child Theme" button do?

WordPress changed the recommended way of handling parent references in child themes. If this plugin detects your child theme was done in the old style, it shows this button. Clicking on it will make the plugin attempt a repair into the new style.

How come the screenshot service just shows a big 404

The most likely scenario is your WordPress site_url isn't publicly accessible from the web.

What's with the debugging/error code on child theme creation?

You have an old version of this plugin, please update to the latest one.

I wrote this plugin back during a talk at WordCamp SF 2011 about CSS Themeing in order to help the person sitting next to me. I just didn't get to some things… for years. Sorry about that! The debugging code didn't affect any behavior — it was a sign of me being lazy and not realizing that the plugin would have tens of thousands of avid users!

The theme screenshot service doesn't seem to be working.

First of all, is the blog accessible from the public Internet? If not, then that is the problem.

But sometimes, even then, mshots seems a bit on the slow side. The plugin uses WordPress.com’s mShots service. You know, I worked at Automattic for years on WordPress.com and I still haven't quite figured out mShots. Eventually I've gotten the animated loading GIF to be replaced by a real retina-ready JPEG screenshot of my blog homepage. Trust me, when it works, it works great! But the experience may be a little like trying to get a vending machine to accept a crumpled dollar bill — Americans know what I mean. Suffice it to say that you might have to hit reload a couple times, or just fiddle around a bit.

Why should I use your plugin and not [_insert competitor here_](https://wordpress.org/plugins/search.php?q=child+theme)

What? People have forked my idea because I left Automattic for Wikimedia three years ago? This means war! Other plugins, you're going down! Steel yourself for the pent-up aggression of a pointy-haired boss being kept away from a programming console for years.

As to why this plugin is the best? OCCT is Coke Classic to every other plugin's New Coke. Experience the original plugin taste your parents knew and loved! Plus, I have four-year old screenshots on my theme page, a way cooler plugin icon, and a baby picture of me and my brother on the banner. Also, this plugin strikes the right balance of features, is free (no "pro" version and not even a PayPal link), and (now that I've figured out how to admin the plugin page), I've been adding volunteers to support it. Even if I sucked into the vortex of middle management again (isn't going to happen, that s--t is EVIL) this plugin will live forever in the hearts and minds of bloggers everywhere!

Which reminds me, if you want to help out, we're cool with that. Like WordPress itself, this is a volunteer endeavor. Contact us in the support pages and we'll hook you up!
