Convert modified parent theme into child theme

You can download a basic Twenty Ten child theme from here.

I need assistance in resolving the following message that appears when I attempt to activate the child theme:

That means you’re declaring – i.e. defining two functions with the same name.

I’m assuming the likely cause is that you have copied/pasted all (or part) of Twenty Ten’s functions.php file into your Twenty Ten Child’s functions.php?

At the very least, you have function twentyten_page_menu_args() {} in both files, which is the cause of this specific error.

Remove it from the Child Theme.

Don’t put anything in the Child Theme that you don’t intend to modify from its original state in the Parent Theme. Most likely, your Child Theme’s functions.php file should be empty (and if so, it doesn’t even need to exist at all).

As for overriding Theme functions: you can only redeclare pluggable functions from the Parent Theme: that is, functions in the Parent Theme that are wrapped in a if ( ! function_exists() {} ) conditional. Or, if they are provided, you can use custom filters.

If none of this makes any sense, you probably shouldn’t be messing with functions.php to begin with.

Oh boy!
That’s how your directory should look like:

wp-content includes the following folders:

• languages
• plugins
• themes
• upgrade
• uploads
• index.php

your themes folder contains only the themes and child-themes.

Also if you create a child-theme and a style.css for it, you have to include the refering theme’s style.css file in the new style sheet:

@import url(“../twentyten/style.css”);

Hope it helps.

There’s no separate plugin for each theme. Plugins are installed into the “wp-content/plugins” directory. It’s a global settings, if that’s the right use of word. Please guys correct me if I’m wrong. 🙂
