Karminowy

I found this part of code in functions.php

function serene_excerpt_more( $more ) {
	return sprintf( '...<a class="read-more" href="%s">%s</a>',
		get_permalink( get_the_ID() ),
		esc_html__( 'Read more', 'Serene' )
	);
}
add_filter( 'excerpt_more', 'serene_excerpt_more' );

Any help?

That code didn’t change anything.

I deleted this:
<?php bloginfo( ‘name’ ); ?>

I deleted code line that was responsible for showing text in header, then replaced it with this code.
<img src=”<?php bloginfo(‘stylesheet_directory’);?>/images/logo.png”/>
After that I pasted logo.png into serene/images/

Sorry for my english.
