Comment (by rimtoo):
The error message you provided indicates that there is an issue with the
WP_Customize_Header_Image_Control class and its process_default_headers()
method being called on a non-object. This error typically occurs when you
attempt to use the Customizer with a theme that doesn't support custom
headers.
Here's a possible solution to handle this error by checking whether the
WP_Customize_Header_Image_Control object exists before calling its
methods:
<?php
if ( class_exists( 'WP_Customize_Header_Image_Control' ) ) {
$custom_image_header = new WP_Customize_Header_Image_Control(
$wp_customize );
if ( is_object( $custom_image_header ) ) {
// Process custom header controls here
}
}
This code snippet checks if the WP_Customize_Header_Image_Control class
exists, and if it does, it attempts to create an instance of it. Then, it
checks if the instance is a valid object before proceeding to process
custom header controls.
