modify the archive page title and add the brand logo

In the mean time I found the solution for point 1:
I copy and modified the function woocommerce_page_title() (Located at includes/wc-template-functions.php)into my child theme’s functions.php

For point 2 I found this: https://docs.woothemes.com/document/woocommerce-display-category-image-on-category-archive/

Hi Valdinia,

I’m sorry for my very late response ??
I hope I can still help you with some useful informations

1. Instead of defining your own woocommerce_page_title() you should use the provided filter woocommerce_page_title, that let you change the title without changing WC default behaviour

This is an example of how it should be used

if( defined( 'YITH_WCBR' ) && ! function_exists( 'yith_wcbr_change_brand_page_title' ) ) {
	function yith_wcbr_change_brand_page_title( $title ) {
		global $wp_query;

		if( is_tax( YITH_WCBR::$brands_taxonomy ) ){
			$title .= ' ' . __( 'products', 'yith_wcrb' );
		}

		return $title;
	}
	add_filter( 'woocommerce_page_title', 'yith_wcbr_change_brand_page_title' );
}

2. I think this is a good resource, and you can implement it. Thank you for sharing it with us ??

Hop this helps
Have a nice day
