Theme Horse

hi levi0322,
We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.

Example to customize the 404.php page

unhook functions

// Unhook default Thematic functions
function unhook_thematic_functions() {
    // Don't forget the position number if the original function has one

remove_action( 'cleanretina_404_content', 'cleanretina_display_404_page_content', 10 );

}
add_action('init','unhook_thematic_functions'); // removes the header content by using hook cleanretina_header

add_action( 'cleanretina_404_content', 'cleanretina_child_display_404_page_content', 10 );
/**
 * function to show the footer info, copyright information
 */
 
 
function attitude_child_display_404_page_content() {      ?>   
<div id="content">
		<header class="entry-header">
			<h1 class="entry-title"><?php _e( 'Error 404-Page NOT Found', 'attitude' ); ?></a></h1>
		</header>
		<div class="entry-content clearfix" >
			<p>Thank you</p> 
		</div><!-- .entry-content -->
	</div><!-- #content -->
  <?php 
}

Hi levi0322,
Yes exactly. Create a child theme folder (cleanretina_child) inside wp-content -> themes
create two file
1> style.css and import the css
2> functions.php
under function.php add the above code then when 404.php page is called it will display thank you. Because there is `<p>Thank you</p>
` You can use any text you want under it.

Thank you!

Hi levi0322,
We can’t create your child theme. We provide only the solution. If still you could not solve it then you may hire a developer to fix it.
Once read it more carefully

Thank you!

Hi levi0322,
Yes this above code must be inside style.css

/*
Theme Name: Clean Retina Child
Theme URI: http://aging-naturally.com/clean-retina-child/
Description: Clean Retina Child Theme
Author: Pauline Downie
Author URI: http://aging-naturally.com
Template: clean-retina
Version: 1.0.0
Tags: light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready
Text Domain: clean-retina-child
*/

@import url(“../clean-retina/style.css”);

/* =Theme customization starts here
————————————————————– */ 

After doing this this will import all the css from your parent theme

Regardless to page 404

Create one functions.php file
after this paste this code

unhook functions

// Unhook default Thematic functions
function unhook_thematic_functions() {
    // Don't forget the position number if the original function has one

remove_action( 'cleanretina_404_content', 'cleanretina_display_404_page_content', 10 );

}
add_action('init','unhook_thematic_functions');

add_action( 'cleanretina_404_content', 'cleanretina_child_display_404_page_content', 10 );

function cleanretina_child_display_404_page_content() {      ?>   
<div id="content">
		<header class="entry-header">
			<h1 class="entry-title"><?php _e( 'Error 404-Page NOT Found', 'attitude' ); ?></a></h1>
		</header>
		<div class="entry-content clearfix" >
			<p>Thank you</p> 
		</div><!-- .entry-content -->
	</div><!-- #content -->
  <?php 
}

Make sure that you have created the child theme folder inside themes folder

Thank you!

hi levi0322,
Just add this functions inside functions.php at the top of the page.

<?php

add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_styles', PHP_INT_MAX);
function enqueue_child_theme_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
    wp_enqueue_style( 'child-style', get_stylesheet_uri(), array('parent-style')  );
}

make sure that your child theme is created or not and from dashboard -> appearance -> themes

If yes then activate the child theme first. Once send you site url too. If still you are unable then you need to hire a developer. Because we don’t ask ftp. And from the dashboard only its not possible to customise the code.

Thank you!
