Duplicate Header on WP E-commerce

This week I found the anomaly on my being created blog. That blog using free version of WP e-commerce plugin to handle our business on sale and purchase of our products. I’m having an issue on the category and products page. The custom image header of my blog is duplicating. The header shows twice. Sure, I have upgraded both WordPress and WP e-commerce to the latest versions but the anomaly is still not resolved in this way

Finally I had to flip through the files of the WP e-commerce plugin and read and pay attention to every functions that exists in those files. Finally, I found what I was looking for after a few days to check the files. I found a command that calls the header in a function that is used by WP e-commerce

We can found that function in the file theme.functions.php (wp-content/plugins/wp-e-commerce/wpsc-includes). The exact function name was wpsc_the_featured_image_fix. To be more clear, please refer to the comparison code below

Original function in WP E-commerce Version 3.8.4

function wpsc_the_featured_image_fix($stuff){
	global $wp_query;
	remove_action('post_thumbnail_html','wpsc_the_featured_image_fix');
	if(isset($wp_query->query_vars['wpsc-product'])){
		$stuff ='';	?>
		<img src="<?php header_image(); ?>" width="<?php echo HEADER_IMAGE_WIDTH; ?>" height="<?php echo HEADER_IMAGE_HEIGHT; ?>" alt="" /> <?php
	}
	return $stuff;
}

add_action('post_thumbnail_html','wpsc_the_featured_image_fix');

Modified function to solve duplicate header on WP E-commerce used by our blog

function wpsc_the_featured_image_fix($stuff){
	global $wp_query;
	remove_action('post_thumbnail_html','wpsc_the_featured_image_fix');
	if(isset($wp_query->query_vars['wpsc-product'])){
		$stuff ='';	?>
		<!-- <img src="<?php //header_image(); ?>" width="<?php //echo HEADER_IMAGE_WIDTH; ?>" height="<?php //echo HEADER_IMAGE_HEIGHT; ?>" alt="" /> --><?php
	}
	return $stuff;

}

add_action('post_thumbnail_html','wpsc_the_featured_image_fix');

This is not really the best way to solve duplicate header on WP E-commerce. But this way has managed to speed up my work in building a new blog using WP E-commerce. Hopefully this way can be useful for you. If you have a better way, please comment here
